US20120214889A1 METHOD FOR THE PRODUCING ANHYDRIDE-CONTAINING VINYL AROMATIC-VINYL CYANIDE COPOLYMERS HAVING REDUCED DIRT PARTICLE CONTENT 审中-公开
生产含有降低二聚体颗粒含量的含羟基芳香族芳族羧酸酯共聚物的方法

METHOD FOR THE PRODUCING ANHYDRIDE-CONTAINING VINYL AROMATIC-VINYL CYANIDE COPOLYMERS HAVING REDUCED DIRT PARTICLE CONTENT
摘要：
The present invention relates to processes for preparing copolymers A) with a reduced soil particle content, comprising 49.2 to 93.2% by weight of structural units which derive from one or more vinylaromatic monomers (component A1)), 6 to 50% by weight of structural units which derive from one or more vinyl cyanides (component A2)), 0.8 to 7% by weight of structural units which derive from one or more dicarboxylic anhydrides (component A3)) and 0 to 25% by weight of structural units which derive from further copolymerizable monomers (component A4)), where the percentages by weight are each based on the total weight of the structural units which derive from components A1), A2), A3) and A4), and together add up to 100% by weight, by bulk or solution polymerization, it being essential to the invention that the mathematical product of the percentages by weight of the structural units which derive from component A2) and the percentages by weight of the structural units which derive from component A3) in the copolymer A) is in the range from 40%2 by weight to 65%2 by weight. The present invention further relates to the copolymers A), to thermoplastic molding materials comprising the copolymers A), to the use of the copolymers A) and of the thermoplastic molding materials, and to the moldings, films, fibers and foams obtainable from the copolymers A) and the thermoplastic molding materials.
摘要（中）：

本发明涉及制备具有减少的土壤颗粒含量的共聚物A）的方法，其包含49.2至93.2重量％的衍生自一种或多种乙烯基芳族单体（组分A1）的结构单元），6至50重量％的结构 衍生自一种或多种乙烯基氰化物（组分A2）的单元），0.8至7重量％的衍生自一种或多种二羧酸酐（组分A3）的结构单元）和0至25重量％的衍生自 进一步的可共聚单体（组分A4）），其中重量百分比各自基于衍生自组分A1），A2），A3）和A4）的结构单元的总重量，并且一起加起来至100重量％ ，通过本体或溶液聚合，对于本发明，从组分A2得到的结构单元的重量百分比的数学乘积和从com得到的结构单元的重量百分比是必要的 共聚物A）中的共聚物A3）在40重量％至65重量％的范围内。 本发明还涉及使用共聚物A）和热塑性成型材料的共聚物A）和包含共聚物A）的热塑性成型材料以及可从共聚物获得的模制品，膜，纤维和泡沫体 A）和热塑性成型材料。
