    • PROBLEM TO BE SOLVED: To provide a method for producing a chlorinated propylene-containing polymer, which includes a step of chlorinating a propylene-containing polymer in a mixed liquid of a chlorine-based solvent and water, and which can provide a target material more efficiently than conventionally.SOLUTION: The method for producing a chlorinated propylene-containing polymer includes (1) a step 1 of dispersing at least one propylene-containing polymer of polypropylene and a propylene-α-olefin copolymer in a mixed liquid of chloroform and water to thereby obtain a dispersion liquid, (2) a step 2 of introducing chlorine gas in the dispersion liquid under heating at a temperature of ≤130°C of the dispersion liquid to thereby chlorinate the propylene-containing polymer, (3) a step 3 of adding a water-insoluble epoxy group-containing compound to the reaction liquid obtained in the step 2, leaving the resultant untouched, and thereafter, preparatively collecting a chloroform-containing phase, and (4) a step 4 of distilling chloroform out of the chloroform-containing phase to thereby obtain the chlorinated propylene-containing polymer.
    • 解决的问题:提供一种含氯化丙烯聚合物的制造方法,其包括在氯系溶剂和水的混合液中氯化含丙烯的聚合物的步骤,其可以提供 目标材料比传统方法更有效。 解决方案:含氯化丙烯聚合物的制造方法包括:(1)在氯仿和水的混合液中分散至少一种含丙烯的聚丙烯和丙烯-α-烯烃共聚物的步骤1至 从而得到分散液,(2)在分散液的〜130℃的温度下加热分散液中的氯气的步骤2,使含丙烯聚合物进行氯化,(3)步骤3 向步骤2中得到的反应液中加入不溶于水的环氧基化合物,使其不变,然后制备性地收集含氯仿的相,和(4)将氯仿从氯仿中蒸馏出的步骤4 从而得到含氯化丙烯的聚合物。 版权所有(C)2013,JPO&INPIT
