阅读说明：本技术 收缩率低的苯乙烯共聚物混合物 (Low shrinkage styrenic copolymer blends ) 是由 T·舒尔茨 于 2018-03-14 设计创作，主要内容包括：本发明涉及一种苯乙烯共聚物A和共聚物B的聚合物共混物,其中苯乙烯共聚物A选自苯乙烯丙烯腈共聚物(SAN),苯乙烯丙烯腈马来酸酐三元共聚物(SMA),苯乙烯丙烯酸共聚物,丙烯腈丁二烯苯乙烯三元共聚物(ABS),丙烯腈丁二烯苯乙烯三元共聚物与聚酰胺(ABS/PA)和丙烯腈苯乙烯丙烯酸酯三元共聚物(ASA)；共聚物B选自苯乙烯-丁二烯嵌段共聚物(SBC)和苯乙烯-异戊二烯嵌段共聚物(SIS)；与纯苯乙烯共聚物A的模制收缩率相比,所述聚合物共混物的模制收缩率降低了至少5％。本发明还涉及聚合物共混物的制备方法以及该聚合物共混物在注塑工艺中的用途。(The present invention relates to a polymer blend of a styrene copolymer a and a copolymer B, wherein the styrene copolymer a is selected from the group consisting of styrene acrylonitrile copolymer (SAN), styrene acrylonitrile maleic anhydride terpolymer (SMA), styrene acrylic acid copolymer, acrylonitrile butadiene styrene terpolymer (ABS), acrylonitrile butadiene styrene terpolymer with polyamide (ABS/PA) and acrylonitrile styrene acrylate terpolymer (ASA); the copolymer B is selected from styrene-butadiene block copolymers (SBC) and styrene-isoprene block copolymers (SIS); the polymer blend has a reduction in mold shrinkage of at least 5% as compared to the mold shrinkage of pure styrene copolymer a. The invention also relates to a method for producing the polymer blend and to the use of the polymer blend in injection molding processes.)
