摘要： Specific low density polyethylene articles that exhibit improved physical characteristics and other benefits over previously made articles produced by less efficient means are provided. Such articles require the presence of saturated or unsaturated bicyclic dicarboxylate nucleating agents that impart increased crystallization temperatures, permit lower manufacturing cycle times, and, most importantly, cause a drastic reduction in warpage at quick cooling times during production. These resultant articles thus can be produced more efficiently with reliable low-warpage characteristics.

摘要翻译： 提供了具有较好的物理特性的特定的低密度聚乙烯制品以及其它优于先前制得的制品的效率低的手段。 这样的制品需要存在饱和或不饱和的双环二羧酸成核剂，其赋予增加的结晶温度，允许较低的制造周期时间，并且最重要的是在生产期间快速冷却时间引起翘曲的急剧减少。 因此，可以以可靠的低翘曲特性更有效地制造这些所得制品。

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。
