    • This invention relates to a fluid dispersion of at least one dibenzylidene sorbitol acetal derivative. The sorbitol acetal derivative is useful as a clarifying agent for polyolefins and the inventive fluid dispersion permits improvements in the handling and processing of and mixing within the polyolefin composition. The inventive dispersion must be shelf stable, retain its nucleating effects, be compatible with polypropylene (and other polyolefins), and possess both short-term and long-term viscosities which permit acceptable transport through a standard polyolefin-manufacturing peristaltic pump. The preferred inventive dispersion thus comprises 3,4-DMDBS and at least one ethoxylated nonionic surfactant having an HLB of greater than about 8.5. Preferred surfactants include those selected from the group consisting essentially of ethoxylated sorbitan (C8-C22) monoesters and ethoxylated nonyl-phenol ethers. The inventive dispersion may be introduced within any polyolefin composition, preferably polypropylene, which may then be molded into an shape or form. A method of producing a polyolefin plastic utilizing the inventive dispersion is also provided.
    • 本发明涉及至少一种二亚苄基山梨糖醇缩醛衍生物的流体分散体。 山梨糖醇缩醛衍生物可用作聚烯烃的澄清剂,并且本发明的流体分散体可以改进聚烯烃组合物的处理和加工以及混合。 本发明的分散体必须是稳定的,保持其成核作用,与聚丙烯(和其它聚烯烃)相容,并且具有短期和长期粘度,这允许通过标准聚烯烃制造蠕动泵可接受的运输。 因此,优选的本发明分散体包含3,4-DMDBS和至少一种HLB大于约8.5的乙氧基化非离子表面活性剂。 优选的表面活性剂包括选自乙氧基化脱水山梨糖醇(C8-C22)单酯和乙氧基化壬基酚醚的那些基团。 本发明的分散体可以引入任何聚烯烃组合物,优选聚丙烯中,然后可以将其模塑成任何形状或形式。 还提供了利用本发明的分散体生产聚烯烃塑料的方法。
