摘要： Thermoplastic articles may be manufactured having a high degree of visual appeal to consumers. Clarifying agents may be employed as additives in such thermoplastic articles to produce high clarity articles. A coloring agent may be mixed with clarifying agents to form a first blend, and then such a first blend may be applied in very low loadings to form a clarified polymeric article. It is possible to achieve an observable visual benefit while using very low loadings of coloring agent in a polyolefin, such as polypropylene. Carbon black is a pigment that may provide such observable benefits in polypropylene.
摘要翻译：可以制造对消费者具有高度视觉吸引力的热塑性制品。澄清剂可用作这种热塑性制品中的添加剂以产生高透明度制品。着色剂可以与澄清剂混合以形成第一共混物，然后这种第一共混物可以非常低的载量施加以形成澄清的聚合物制品。在聚烯烃（例如聚丙烯）中使用非常低的着色剂负载的情况下，可以实现可观察到的视觉效果。炭黑是可以在聚丙烯中提供这种可观察益处的颜料。

摘要： A specific combination of two different polyolefin clarifying and nucleating agents, namely 3,4-dimethyldibenzylidene sorbitol and p-methyldibenzylidene sorbitol is provided. Such a combination surprisingly provides improved clarification and crystallization temperatures to polypropylene articles and formulations, better than bis-p-methyldibenzylidene sorbitol alone and equivalent or better than 3,4-dimethyldibenzylidene sorbitol. Such a combination of compounds thus permits the utilization of a new additive for the purpose of modifying polyolefin properties, such as polypropylene clarification and nucleation. The inventive combination may be introduced within any polyolefin composition, again preferably polypropylene, which may then be molded into any shape or form. A method of producing a polyolefin plastic utilizing the inventive combination of compounds is also provided.
摘要翻译：提供了两种不同的聚烯烃澄清和成核剂，即3,4-二甲基二亚苄基山梨糖醇和对甲基二亚苄基山梨糖醇的具体组合。这种组合令人惊奇地提供了聚丙烯制品和制剂的改进的澄清和结晶温度，优于单独的双 - 对甲基二亚苄基山梨醇，等同于或优于3,4-二甲基二亚苄基山梨糖醇。因此，这样的化合物组合物可以利用新的添加剂来改善聚烯烃的性能，例如聚丙烯澄清和成核。本发明的组合可以引入任何聚烯烃组合物中，再次优选聚丙烯，然后可以将其模制成任何形状或形式。还提供了利用本发明化合物组合生产聚烯烃塑料的方法。

摘要： Specific methods of inducing high nucleation rates in thermoplastics, such as polyolefins, and particularly, though not necessarily, polypropylenes, through the introduction of two different compounds that are substantially soluble within the target molten thermoplastic resin (such as, as one non-limiting example, an added compound including at least one acid group and an added organic salt) are provided. Such introduced components react to form a nucleating agent in situ within such a target molten thermoplastic resin which is then allowed to cool. Preferably, one compound is an acid, preferably bicyclic (i.e., two cyclic systems sharing at least three carbon atoms) or monocycloaliphatic (i.e., a single, saturated ring system) in nature, such as, without limitation, bicyclo[2.2.1]heptane dicarboxylic acid or hexahydrophthalic acid, and the other compound is an organic salt, such as a carboxylate, sulfonate, phosphate, oxalate, and the like, and more preferably selected from the group consisting of metal C8-C22 esters. Such a production method thus provides a manner of generating in situ the desired nucleating agent through reaction of such soluble compounds. Kits (e.g., masterbatch methods, for example) comprising such components for easy introduction within target molten polyolefin resins are also contemplated within this invention.
摘要翻译：通过引入基本上可溶于目标熔融热塑性树脂的两种不同的化合物（例如作为一个非限制性实例），在热塑性塑料如聚烯烃，特别是但不一定是聚丙烯中诱导高成核速率的具体方法，含有至少一个酸基和添加的有机盐的添加化合物）。这种引入的组分反应以在这样的目标熔融热塑性树脂中就地形成成核剂，然后使其冷却。优选地，一种化合物在本质上是酸，优选双环（即，共享至少三个碳原子的两个环状体系）或单环脂族（即单个饱和环系），例如但不限于双环[2.2.1] 庚烷二羧酸或六氢邻苯二甲酸，另一种化合物为有机盐，如羧酸盐，磺酸盐，磷酸盐，草酸盐等，更优选选自金属C 8 -C 22酯。因此，这种制备方法提供了通过这些可溶性化合物的反应原位产生所需成核剂的方式。在本发明中也考虑了包含这些组分以用于在目标熔融聚烯烃树脂内容易引入的组分（例如，母料方法）。
