摘要： A vinyl chloride resin composition comprises:(1) 100 parts of vinyl chloride polymer; and(2) 0.1 to 30 parts of a polymer processing aid comprising:(A) 40 to 90 parts of a copolymer comprising80 to 100% of an alkyl methacrylate, and0 to 20% of a monomer copolymerizable therewith; and(B) 60 to 10 parts of a copolymer comprising20 to 79% of an alkyl methacrylate,20 to 79% of an aromatic vinyl monomer,1 to 49% of diolefin, and0 to 20% of a monomer copolymerizable therewith,the copolymers (A) and (B) having been wet-blended to provide 100 parts of the polymer processing aid, all quantities expressed in parts and percentages being by weight.This vinyl chloride resin composition comprising a novel polymer processing aid not only shows an increased gelation rate, yields less ungelled particles and possesses excellent processability such as an increased elongation at a high temperature, but particularly possesses excellent mechanical properties because the impact strength of the composition is not appreciably lowered by the addition of the polymer processing aid.
摘要翻译：氯乙烯树脂组合物包括：（1）100份氯乙烯聚合物; （2）0.1〜30份聚合物加工助剂，其包含：（A）40〜90份包含80〜100％的甲基丙烯酸烷基酯和0〜20％的可与其共聚的单体的共聚物; 和（B）60〜10份包含20〜79％的甲基丙烯酸烷基酯，20〜79％的芳族乙烯基单体，1〜49％的二烯烃和0〜20％的可与其共聚的单体的共聚物，共聚物（A）和（B）已经湿共混以提供100份聚合物加工助剂，所有数量以份数和百分比表示，以重量计。包含新型聚合物加工助剂的氯乙烯树脂组合物不仅表现出增加的凝胶化速率，产生较少的未凝胶化颗粒，并且具有优异的加工性能，例如在高温下增加的伸长率，但是由于组合物的冲击强度，特别是具有优异的机械性能通过加入聚合物加工助剂不会明显降低。

摘要： A composition comprising polyvinyl chloride and a novel polymer processing aid is provided. The polymer processing aid can be obtained either by blending in latex form an alkyl methacrylate copolymer (A) and a copolymer (B) comprising as its essential constituents an alkyl methacrylate, a dialkyl itaconate or an alkyl acrylate, and a diolefin, or by copolymerizing one of the copolymers in the presence of the other copolymer.The polymer processing aid thus obtained improves the processability of the vinyl chloride resin composition with less reduction in impact strength.
摘要翻译：提供了包含聚氯乙烯和新型聚合物加工助剂的组合物。聚合物加工助剂可以通过将乳液形式的甲基丙烯酸烷基酯共聚物（A）和包含作为其主要组分的基本组分的共聚物（B）与甲基丙烯酸烷基酯，衣康酸二烷基酯或丙烯酸烷基酯和二烯烃共聚，或通过共聚在其他共聚物存在下的共聚物之一。由此获得的聚合物加工助剂改善了氯乙烯树脂组合物的冲击强度降低较少的加工性能。
