    • A specific combination of two different polyolefin clarifying and nucleating agents, namely bis(3,4-dimethyldibenzylidene) sorbitol (3,4-DMDBS) and bis(3,4-dichlorodibenzylidene) sorbitol (3,4-DCDBS). Such a combination surprisingly provides improved clarification comparable to polypropylene articles and formulations, better than DCDBS alone and equivalent or better than DMDBS alone. 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.
    • 两种不同的聚烯烃澄清和成核剂,即双(3,4-二甲基二亚苄基)山梨醇(3,4-DMDBS)和双(3,4-二氯二亚苄基)山梨糖醇(3,4-DCDBS)的具体组合。 这种组合令人惊奇地提供了与聚丙烯制品和制剂相当的改进的澄清,优于单独的DCDBS,等同于或优于单独的DMDBS。 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。

    • This invention relates to a process for preparing alditol acetals, such as dibenzylidene sorbitols, monobenzylidene sorbitols, and the like, through the reaction of unsubstituted or substituted benzaldehydes with alditols (such as sorbitol, xylitol, and ribitol) in the presence of a mineral acid and at least one surfactant having at least one pendant group of 6 carbon chains in length. Such a reaction provides a cost-effective, relatively safe procedure that provides excellent high yields of alditol acetal product. Furthermore, such a specific reaction is also the best known procedure for the production of certain compounds which can be easily separated from other formed isomers. Additionally, such a procedure facilitates the production of certain asymmetric alditol acetal compounds and compositions in acceptable yields as well. Such alditol acetals are useful as nucleating and clarifying agents for polyolefin formulations and articles, as one example.
    • 本发明涉及通过在无机酸存在下,未取代或取代的苯甲醛与糖醇(如山梨糖醇,木糖醇和核糖醇)的反应制备二醇二醇,例如二亚苄基山梨糖醇,一亚苄基山梨糖醇等的方法。 和至少一种具有至少一个6个碳链侧基的表面活性剂。 这种反应提供了一种经济有效的相对安全的方法,其提供优异的高产率的醛缩醛缩醛产物。 此外,这种特异性反应也是生产某些可以容易地与其它形成的异构体分离的化合物的已知方法。 另外,这样的方法也有助于生产某些不对称的醛缩醛缩醛化合物和组合物的可接受的产率。 作为一个实例,这种醛醇缩醛可用作聚烯烃配方和制品的成核剂和澄清剂。
