摘要： A thermoplastic molding composition is composed of a linear poly(oxymethylene) and a graft copolymer the side chains of which consist essentially of oxymethylene groups. The said graft copolymer acts as a nucleating agent; its effectiveness is dependent on its amount, molecular weight and degree of grafting. Molded articles made of said composition show improved mechanical properties.

摘要： A modified thermoplastic molding composition based on polyacetal prepared by polymerizing trioxane in the presence of a polyether by means of a catalyst; the polyether is a copolymer of at least 2 different cyclic ethers. The polymerization may also take place in the presence of additional monomers, suitable for the copolymerization with trioxane. The molding composition is suitable for the manufacture of different kinds of shaped articles, especially machine parts.
摘要翻译： 一种基于聚缩醛的改性热塑性模塑组合物，其通过在聚醚存在下通过催化剂聚合三恶烷而制备; 聚醚是至少2种不同的环醚的共聚物。 聚合还可以在适用于与三恶烷共聚的其它单体的存在下进行。 该模塑组合物适用于制造不同种类的成型制品，特别是机器部件。
