    • Disclosed is a non-rigid vinyl chloride polymer composition comprising 100 weight parts of a vinyl chloride polymer resin, 5-50 weight parts of a graft copolymer modifier and 10-300 weight parts of a plasticizer. The graft copolymer modifier is obtained by graft-polymerizing 25-150 weight parts of an alkyl ester of methacrylic acid having 1 to 4 carbon atoms in the alkyl group or a monomer mixture composed of at least more than 50% by weight of said alkyl ester of methacrylic acid onto 100 weight parts of an acrylic elastomer having a swelling degree of 5 to 25 so that the grafting ratio is not larger than 50%. The acrylic elastomer is obtained by polymerizing a mixture comprising an alkyl ester of acrylic acid having 2 to 10 carbon atoms in the alkyl group or a monomer mixture composed of at least 50% by weight of said alkyl ester of acrylic acid, and a polyfunctional crosslinking agent. The non-rigid vinyl chloride polymer composition has excellent weatherability and impact resistance, and exhibits a good molding processability.
    • 公开了一种非刚性氯乙烯聚合物组合物,其包含100重量份的氯乙烯聚合物树脂,5-50重量份的接枝共聚物改性剂和10-300重量份的增塑剂。 接枝共聚物改性剂通过在烷基中接枝聚合25-150重量份的具有1至4个碳原子的甲基丙烯酸的烷基酯或由至少大于50重量%的所述烷基酯组成的单体混合物 的甲基丙烯酸加入到100重量份的溶胀度为5〜25的丙烯酸类弹性体中,使得接枝率不大于50%。 丙烯酸弹性体是通过在烷基中聚合含有2-10个碳原子的丙烯酸烷基酯的混合物或由至少50重量%的所述丙烯酸烷基酯组成的单体混合物和多官能交联 代理商 非刚性氯乙烯聚合物组合物具有优异的耐候性和耐冲击性,并且表现出良好的成型加工性。
