摘要：The catalyst consists of cuprous halide, alpha, alpha'-dipyridine or its derivative and Lewis acid, and it enables the polymerization of active free radicals at relatively lower temperature and shortens the reaction period by 50% compared with available technology. Common ethenyl monomer can be polymerized in the presence of the catalyst to obtain polymer with controllable narrowly distributed molecular weight in the range of 1000-100000 or copolymer with controllable block, atactic, grafted and other chemical structure.
