Patent ID: 8742045

Claim:
A living radical polymerization method, comprising: a step of halogenating an alcohol compound, wherein the atom bound to the hydroxyl group in the alcohol compound is carbon, with a halogenating agent capable of halogenating hydrogen of a hydroxyl group of an alcohol to produce a halogenated derivative compound wherein the hydrogen in the hydroxyl group is substituted with a halogen, wherein the atom bound to the hydroxyl group of the alcohol compound has a non-conjugated structure, and a step of conducting living radical polymerization of a monomer having a radical-reactive unsaturated bond using the halogenated derivative compound as a dormant species for the living radical polymerization, wherein a radical produced by elimination of a halogen from the halogenated derivative compound is allowed to react with the unsaturated bond of the monomer, wherein the halogenating agent has a structure of the following formula 4, R 2 —C(═O)—NX—C(═O)—R 3 , Formula 4 wherein X is a halogen, R 2 and R 3 are each independently an arbitrary substituent, R 2 and R 3 may be linked with each other to form a ring structure, and the halogenating agent acts also as a catalyst for living radical polymerization.
