摘要： A film that is both elastic and water-sensitive (e.g., water-soluble, water-dispersible, etc.) in that it loses its integrity over time in the presence of water is provided. To achieve these dual attributes, the film contains an olefinic elastomer and a water-soluble polymer. Although these polymers are normally chemically incompatible due to their different polarities, the present inventors have discovered that phase separation may be minimized by selectively controlling certain aspects of the film, such as the nature of the polyolefin, water-soluble polymer, and other film components, the relative amount of the film components, and so forth. For example, certain water-soluble polymers may be selected that have a low molecular weight and viscosity to enhance their melt compatibility with nonpolar polyolefins. This, in turn, may result in a film that is generally free of separate phases, which would otherwise limit the ability of the water-soluble polymer to contact water and disperse.

摘要： A biodegradable and renewable film that may be employed in a wide variety of applications is provided. The film is formed from a thermoplastic composition that contains at least one starch and at least one plant protein. Even at a high renewable material content, the present inventors have discovered that films may be readily formed from plant proteins and starches by selectively controlling the individual amount of the starch and plant proteins, the nature of the starch and plant proteins, and other components used in the film. Balancing the amount of starches and plant proteins within a certain range, for instance, can reduce the likelihood of plant protein aggregation and enhance the ability of the composition to be melt processed. The composition also contains at least one plasticizer that improves the thermoplastic nature of the protein and starch components. The selection of the plasticizer may also help reduce the tendency of the plant protein to aggregate during melt processing. For example, a relatively acidic plasticizer (e.g., carboxylic acid) may be employed in certain embodiments to minimize the formation of disulfide bonds in a gluten protein, and thereby decrease its tendency to aggregate.

摘要： A film that contains a thermoplastic polyurethane and water-soluble polymer is provided. The film is both elastic and water-sensitive (e.g., water-soluble, water- dispersible, etc.) in that it loses its integrity over time in the presence of water. The dual attributes of elasticity and water-sensitivity may be achieved by reducing the tendency of the thermoplastic polyurethane and water-soluble polymer to form separate phases. Namely, phase separation may cause the elastomer to act as a barrier and limit the ability of the water-soluble polymer to contact water and thereby disperse. To minimize such phase separation, a variety of aspects of the film construction may be selectively controlled, such as the nature of the thermoplastic polyurethane and water-soluble polymer, the relative amount of each component, and so forth. For example, thermoplastic polyurethanes are polar in nature and thus may be generally compatible with water-soluble polymers (e.g., polyvinyl alcohol), which are also polar in nature. Further, water-soluble polymers having a relatively low molecular weight and viscosity typically possess better melt compatibility with polar thermoplastic polyurethanes. By carefully controlling the nature of the polymers used to form the film, the present inventors have discovered that a film may be formed that is generally free of distinct phases.
摘要翻译：提供含有热塑性聚氨酯和水溶性聚合物的薄膜。该膜既弹性又具有水敏性（例如水溶性，水分散性等），因为它在水的存在下随时间失去其完整性。弹性和水敏性的双重属性可以通过降低热塑性聚氨酯和水溶性聚合物形成分离相的趋势来实现。也就是说，相分离可能导致弹性体作为屏障，并限制了水溶性聚合物与水接触从而分散的能力。为了最小化这种相分离，可以选择性地控制膜构造的各种方面，例如热塑性聚氨酯和水溶性聚合物的性质，各组分的相对量等。例如，热塑性聚氨酯本质上是极性的，因此通常可与水溶性聚合物（例如聚乙烯醇）相容，其性质也是极性的。此外，具有相对较低分子量和粘度的水溶性聚合物通常具有与极性热塑性聚氨酯更好的熔融相容性。通过仔细地控制用于形成膜的聚合物的性质，本发明人已经发现可以形成通常没有不同相的膜。

摘要： An injection molding material that includes a renewable resin containing a combination of renewable polymers (e.g., starch and plant protein) and a plasticizer is provided. Although such compounds are normally difficult to process into thermoplastics, the present inventors have discovered that injection molding materials may nevertheless be formed by melt blending the renewable resin with a synthetic resin (e.g., polyolefin) while selectively controlling the nature of the resins and their relative concentrations. In this manner, a morphology may be achieved in which the renewable resin is present as a discontinuous phase that is dispersed within a continuous phase of the synthetic resin (e.g., "island-in-the-sea" morphology). The discontinuous and continuous phases may each constitute from about 30 vol.% to about 70 vol.%, and in some embodiments, from about 40 vol.% to about 60 vol.%. With such a morphology, the continuity of the synthetic resin can minimize the aggregate properties of the renewable resin such that the molding material possesses melt properties similar to that of the synthetic resin. Further, this morphology may also minimize the need to use different molding tools as the shrinkage properties of the overall composition may be substantially similar to that of the synthetic resin.
摘要翻译：提供了一种注射成型材料，其包括含有可再生聚合物（例如淀粉和植物蛋白）和增塑剂的组合的可再生树脂。虽然这些化合物通常难以加工成热塑性塑料，但是本发明人已经发现，注射成型材料可以通过将可再生树脂与合成树脂（例如聚烯烃）熔融共混而形成，同时选择性地控制树脂的性质及其相对浓度。以这种方式，可以实现其中可再生树脂作为分散在合成树脂的连续相中的不连续相（例如“海岛”形态）存在的形态。不连续和连续相可以各自构成约30体积％至约70体积％，在一些实施方案中为约40体积％至约60体积％。通过这种形态，合成树脂的连续性可以使可再生树脂的聚集性能最小化，使得成型材料具有与合成树脂类似的熔体性质。此外，由于整个组合物的收缩性能可以基本上类似于合成树脂的收缩特性，所以这种形态还可以最小化使用不同的模制工具的需要。

摘要： A method for forming a composition that includes mixing an antimicrobially active botanical oil (e.g., thymol, carvacrol, etc.) and a modified starch polymer within a melt blending device (e.g., extruder) is provided. Unlike the problems associated with proteins, the use of starch polymers allows for a greater degree of flexibility in the processing conditions and is still able to achieve good properties in the resulting composition. The present inventors have also discovered that a plasticizer may be employed to facilitate melt processing of the starch, as well as to enhance the ability of the botanical oil to flow into the internal structure of the starch where it can be retained in a stable manner. The composition is also typically generally free of solvents. In this manner, the starch will not generally disperse before use and prematurely release the botanical oil. Due to the water sensitivity of the modified starch, however, it may be subsequently dispersed by moisture when it is desired to release the botanical oil.
摘要翻译：提供了一种形成组合物的方法，其包括在熔融共混装置（例如挤出机）中混合抗微生物活性植物油（例如百里酚，香芹酚等）和改性淀粉聚合物。与蛋白质相关的问题不同，淀粉聚合物的使用允许在加工条件下具有更大程度的柔性，并且仍能在所得组合物中获得良好的性能。本发明人还发现，可以使用增塑剂来促进淀粉的熔融加工，以及提高植物油流入淀粉内部结构的能力，其中它可以以稳定的方式保留。组合物通常通常也不含溶剂。以这种方式，淀粉通常不会在使用前分散并且过早地释放植物油。然而，由于改性淀粉的水敏感性，当需要释放植物油时，随后可以通过水分分散。

摘要： A fiber formed from a thermoplastic composition that contains a thermoplastic starch and an aliphatic-aromatic copolyester is provided. The copolyester enhances the strength of the starch-containing fibers and also facilitates the ability of the starch to be melt processed. Due to its relatively low melting point, the aliphatic-aromatic copolyester may also be extruded with the thermoplastic starch at a temperature that is low enough to avoid substantial removal of the moisture found in the starch. Furthermore, the aliphatic-aromatic copolyester is also modified with an alcohol so that it contains one or more hydroxyalkyl or alkyl terminal groups. By selectively controlling the conditions of the alcoholysis reaction (e.g., alcohol and copolymer concentrations, temperature, etc.), the resulting modified aliphatic-aromatic copolyester may have a molecular weight that is relatively low. Such low molecular weight polymers have the combination of a higher melt flow index and lower apparent viscosity, which is useful in a wide variety of fiber forming applications, such as in the meltblowing of nonwoven webs.
摘要翻译：提供由含有热塑性淀粉和脂肪族 - 芳香族共聚酯的热塑性组合物形成的纤维。共聚酯增强了含淀粉纤维的强度，并且促进了淀粉熔融加工的能力。由于其相对低的熔点，脂肪族 - 芳族共聚酯也可以在足够低的温度下与热塑性淀粉一起挤出，以避免显着除去在淀粉中发现的水分。此外，脂族 - 芳族共聚酯也用醇改性，使得其含有一个或多个羟烷基或烷基端基。通过选择性地控制醇解反应的条件（例如醇和共聚物浓度，温度等），所得改性的脂肪族 - 芳族共聚酯的分子量可以相对较低。这种低分子量聚合物具有更高的熔体流动指数和较低的表观粘度的组合，其可用于各种各样的纤维形成应用中，例如在非织造纤维网的熔喷中。

摘要： A film that is both biodegradable and flushable, and yet can still act as a barrier to water or other fluids during use, is provided. More particularly, the film contains a water-dispersible core layer that helps the film to lose its integrity after being flushed, as well as a water-barrier skin layer that helps maintain the integrity of the film during use. The nature and relative concentration of the components in the water-barrier layer are selectively controlled to achieve a combination of different functions. That is, the majority of the polymers employed in the water- barrier layer are biodegradable polymers that can be degraded by microorganisms while in an aqueous environment (e.g., septic tank, water treatment facility, etc.). To even further enhance the overall renewability of the layer, a relatively high amount of the biodegradable polymers are starch polymers, which are also renewable. The starch polymers can also minimize the degree of stickiness in the film, which can sometimes result from certain types of synthetic polymers. Even at a high starch content, the present inventors have discovered that films may still be readily formed by using synthetic biodegradable polyesters in combination with the starch to facilitate melt processing.

摘要： A meit-extruded substrate (e.g., fiim, nonwoven web, etc.) that contains a thermoplastic starch formed from a starch and plasticizer is provided. The starch and plasticizer are melt blended together in the presence of a weak organic acid (e.g., lactic acid, formic acid, acetic acid, etc.). By selectively controlling certain parameters of the melt blending process (e.g., extrusion temperature, content of the components, etc.), the present inventors have discovered that the starch may be hydrolyzed in a highly efficient manner to form compositions having a comparably lower weight average molecular weight, polydispersity index, and viscosity, which are particularly suitable for use in the formation of melt-extruded substrates.
