    • A high molecular weight copolymer of a conjugated diolefin and vinyl chloride in which the vinyl chloride content is from 5 mol up to 50 mol percent relative to the total monomers and the vinyl chloride unit is distributed at random in the molecule chain, and a manufacturing process for such copolymer by carrying out the copolymerization by adding a particular catalyst in the presence of at least the vinyl chloride monomer, in a halogenated hydrocarbon as solvent, at a temperature of -100* to 80*C so that the molar ratio of said catalyst to the total amount of the monomers as charged is 0.05 to 0.0001. The catalyst is any acidic Friedel-Crafts metal halide compound wherein the metal belongs to Group II to VIII of the Periodic Table or alkylaluminum halide compound of the general formula, A1 Rn X3 n wherein R represents an alkyl group, X represents a halogen atom and n represents 1 or 1.5.
    • 共轭二烯烃和氯乙烯的高分子量共聚物,其中相对于总单体和氯乙烯单元的氯乙烯含量为5摩尔至50摩尔%,在分子链中随机分布,制造过程 对于这种共聚物,通过在至少氯乙烯单体的存在下,在卤代烃作为溶剂中,在-100〜80℃的温度下,通过加入特定的催化剂进行共聚,使得所述催化剂的摩尔比 相对于所加入的单体的总量为0.05〜0.0001。 该催化剂是任何酸性Friedel-Crafts金属卤化物,其中金属属于元素周期表第Ⅱ至VIII族或通式为Al Rn X3-n的烷基铝卤化物,其中R表示烷基,X表示卤素原子 n表示1或1.5。
