    • A flame retardant copolymer is provided to ensure excellent flame retardancy without input of additional flame retardants and to prepare an environment-friendly thermoplastic resin composition without the degradation of mechanical properties and the generation of toxic gas. A flame retardant copolymer comprises (a) 5~98 weight% of a vinyl cyanide monomer, (b) 1~94 weight% of an aromatic vinyl monomer, and (c) 1~30 weight% of a vinyl group-containing phosphorus monomer as repeating units. A flame retardant thermoplastic resin composition comprises 100 parts by weight of the flame retardant copolymer and 0.001-50 parts by weight of an impact modifier selected from a rubber-modified graft copolymer, an olefin copolymer, and their mixture. The phosphorus content of the vinyl group-containing phosphorus monomer is 18~30 weight%. The impact modifier is a g-ABS copolymer or MBS resin.
    • 提供阻燃共聚物以确保优异的阻燃性,而不需要额外的阻燃剂的输入,并且制备环境友好的热塑性树脂组合物,而不会降低机械性能和产生有毒气体。 一种阻燃共聚物包括(a)5〜98重量%的乙烯基氰单体,(b)1〜94重量%的芳族乙烯基单体,和(c)1〜30重量%的含乙烯基的磷单体 作为重复单元。 阻燃热塑性树脂组合物包含100重量份的阻燃共聚物和0.001-50重量份的选自橡胶改性的接枝共聚物,烯烃共聚物及其混合物的抗冲改性剂。 含乙烯基的磷单体的磷含量为18〜30重量%。 抗冲改性剂是g-ABS共聚物或MBS树脂。
