This invention relates to plastic additives which are useful as nucleating agents and which are especially useful for improving the optical properties of polymeric materials. More particularly, this invention relates to certain bis-halogen-alkyl-benzylidene alditol acetals and polymer compositions thereof which are useful as materials for food or cosmetic containers and packaging. These bis-halogen-alkylbenzylidene alditol acetals are also useful as gelling agents for organic solvents, particularly those used in the preparation of antiperspirant gel sticks.
本发明涉及可用作成核剂的塑料添加剂,特别适用于改善聚合材料的光学性能。更具体地说,本发明涉及某些双卤素-烷基-亚苄基醛醇
缩醛及其聚合物组合物,它们可用作食品或化妆品容器和包装的材料。这些双卤代烷基亚苄基醛糖醇
乙缩醛还可用作有机溶剂的胶凝剂,特别是用于制备止汗剂凝胶棒的胶凝剂。
