Heterogeneous polymerization catalyst, process for producing acrylic polymer, and acrylic polymer |
摘要 |
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.
