LIVING RADICAL POLYMERIZATION INITIATOR, METHOD FOR PRODUCING POLYMER, AND POLYMER

摘要

A living radical polymerization initiator represented by general formula (1), which uses a living radical polymerization initiator that comprises, as initiating groups for reactions, two halogen atoms different from each other in reactivity, and which enables different living radical polymerization reactions to proceed with respect to the respective initiating groups. In general formula (1), R1 represents an organic group which is linkable with two or more other organic groups, and which is selected from among an aliphatic group having 1-12 carbon atoms, an aromatic group, a carbonyl group, a sulfonyl group and an organic group obtained by combining two or more of these groups; each of R2, R3, R4 and R5 represents a hydrogen atom or an organic group selected from among an aliphatic group having 1-12 carbon atoms, an aromatic group, a carbonyl group, a carboxyl group and a sulfonyl group; each of X and Y represents a halogen atom; each of m and n represents an integer of 1 or more; and X and Y are different from each other in reactivity with a monomer.
