ABSTRACT:
A method for modifying a polymer by mixing and reacting a polymer (A), a compound (B) having a nitroxide radical in the molecule thereof, a radical initiator (C), and a radical polymerizable monomer (D) in a non-solvent system in a mixed to thereby graft a monomer (D) to the polymer (A), whereby a desired functional group is introduced to the polymer, without a causing decrease in the molecular weight, gelation, or formation of a homopolymer.
