阅读说明：本技术 制备具有改良脱水性的接枝橡胶组合物的方法 (Process for preparing graft rubber compositions having improved dewatering ) 是由 T·舒尔茨 W·菲舍尔 于 2019-07-23 设计创作，主要内容包括：本文提出一种用于产生接枝共聚物组合物的方法,所述方法基于丙烯腈-苯乙烯-丙烯酸酯(ASA)或丙烯腈-丁二烯-苯乙烯(ABS)接枝共聚物。通过乳液聚合和沉淀获得的接枝共聚物在沉淀之后显示了改良的脱水行为。基于这一方法,可获得具有低残余湿度的ASA和ABS接枝共聚物。此外,本发明涉及一种用于产生热塑性模塑组合物的方法,所述组合物包含至少一种热塑性苯乙烯共聚物(特别是苯乙烯-丙烯腈共聚物)、通过所述方法获得的接枝共聚物,以及任选的其它组分。(Presented herein is a process for producing a graft copolymer composition based on acrylonitrile-styrene-acrylate (ASA) or acrylonitrile-butadiene-styrene (ABS) graft copolymers. The graft copolymers obtained by emulsion polymerization and precipitation exhibit improved dewatering behavior after precipitation. Based on this process ASA and ABS graft copolymers with low residual humidity can be obtained. Furthermore, the present invention relates to a process for producing a thermoplastic molding composition comprising at least one thermoplastic styrene copolymer (in particular a styrene-acrylonitrile copolymer), the graft copolymer obtained by the process, and optionally further components.)
