摘要： Polylactic acid fibers formed from a thermoplastic composition that contains polylactic acid and a polymeric toughening additive are provided. The present inventors have discovered that the specific nature of the components and process by which they are blended may be carefully controlled to achieve a composition having desirable morphological features. More particularly, the toughening additive can be dispersed as discrete physical domains within a continuous phase of the polylactic acid. These domains have a particular size, shape, and distribution such that upon fiber drawing, they absorb energy and become elongated. This allows the resulting composition to exhibit a more pliable and softer behavior than the otherwise rigid polylactic acid. Through selective control over the components and method employed, the present inventors have discovered that the resulting fibers may thus exhibit good mechanical properties, both during and after melt spinning.

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： 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.
摘要翻译：提供了具有弹性和水敏性（例如水溶性，水分散性等）的膜，因为它在水的存在下随时间失去其完整性。为了实现这些双重属性，该膜含有烯烃弹性体和水溶性聚合物。虽然这些聚合物由于其极性不同而通常是化学上不相容的，但是本发明人已经发现，通过选择性地控制膜的某些方面，例如聚烯烃，水溶性聚合物和其它膜组分的性质，可以使相分离最小化，膜成分的相对量等。例如，可以选择某些具有低分子量和粘度的水溶性聚合物，以提高它们与非极性聚烯烃的熔融相容性。这又可能导致通常没有分离相的膜，否则这将限制水溶性聚合物与水接触并分散的能力。

摘要： A method for making modified poly(ethylene oxide) by graft polymerizing thereto organic monomers containing a trialkoxy silane functional group or a moiety that reacts with water to form a silanol group, such as methacryloxypropyl trimethoxy silane, onto the poly(ethylene oxide) is disclosed. The graft polymerization is accomplished by mixing the poly(ethylene oxide), the silane-containing monomer(s) and an initiator and applying heat. Preferably, the method is a reactive-extrusion process. After graft polymerization, the modified poly(ethylene oxide) may be exposed or subjected to relatively high moisture conditions, thereby causing crosslinking and formation of a structure that is capable of absorbing relatively large amounts of saline. The resulting modified poly(ethylene oxide) has improved properties over articles similarly processed from unmodified poly(ethylene oxide).

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.

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.
