METHOD FOR PRODUCING POLYMER COMPOUND HAVING STABLE RADICAL

摘要

PROBLEM TO BE SOLVED: To produce a polymer having a sterically hindered nitroxyl radical in a side chain. SOLUTION: The production method comprises dissolving a polymer having a sterically hindered cyclic secondary amine structure in a side chain into an organic solvent which has a low solubility in water and forms a two-phase system with water, and oxidizing the polymer with hydrogen peroxide in the presence of a catalyst solution containing a water-soluble catalyst. Thereby, a polymer having a sterically hindered nitroxyl radical of a high radical concentration in a side chain can be obtained without inclusion of catalysts. COPYRIGHT: (C)2005,JPO&NCIPI
