METHOD OF PRODUCING COMB OR STAR COPOLYMERS USING EPOXY-FUNCTIONALIZED NITROXYLETHERS

摘要

The present invention provides a method of attaching a polymeric side chain differing in polarity and chemical structure from the backbone and forming a comb or star copolymer structure. In particular the process provides a metho d of polymerizing in a first step a polymer back bone from epoxy group containing monomers and in a second step polymerizing under controlled radic al conditions a comb or star structure onto this back bone.
