NITROGENOUS GRAFT COPOLYMERS,HYBRID COPOLYMERS OF SUCH GRAFT COPOLYMERS WITH RANDOM NITROGENOUS COPOLYMERS,AND METHODS FOR THEIR PREPARATION

摘要

Graft copolymers of nitrogenous monomer(s) on polymeric substrates, and their methods of preparation, are provided. The graft copolymers are produced by polymerizing monomers comprising one or more vinyl monomer into a polymeric substrate, and then grafting one or more nitrogenous monomer onto the polymeric substrate. Hybrid copolymers of a nitrogenous grafted copolymer with a nitrogenous random polymer, and methods for their preparation, are also provided. the hybrid copolymers can be prepared by first forming the nitrogenous graft copolymer and then copolymerizing additional constituent vinyl monomer(s) with residual nitrogenous monomer(s) to form the hybrid copolymer.
