    • A process for producing an acrylic polymer capable of providing a polymer controlled in molecular weight and free of colorization, and a heterogeneous polymerization catalyst used in the process for producing an acrylic polymer are provided. The heterogeneous polymerization catalyst contains (A) a radical generating substance, (B) a metallic halide containing a metallic element selected from the group consisting of the Group 4 to Group 12 elements and a halogen element selected from the group consisting of chlorine, bromine and iodine, and (C) a carrier carrying a ligand capable of forming a coordination bond with the metallic halide (B). The process for producing an acrylic polymer contains a step of polymerizing a monomer containing at least an acrylate and/or a methacrylate in the presence of the heterogeneous polymerization catalyst.
    • 提供了能够提供控制分子量且不着色的聚合物的丙烯酸类聚合物的制备方法,以及用于制备丙烯酸类聚合物的方法中使用的非均相聚合催化剂。 非均相聚合催化剂含有(A)自由基产生物质,(B)含有选自第4族至第12族元素的金属元素的金属卤化物和选自氯,溴和 碘,和(C)携带能够与金属卤化物(B)形成配位键的配体的载体。 制备丙烯酸类聚合物的方法包括在非均相聚合催化剂的存在下聚合至少含有丙烯酸酯和/或甲基丙烯酸酯的单体的步骤。
