One comb-graft copolymer and a reactive group-containing preparation method and application

The present invention discloses a comb-graft copolymer and a reactive group-containing preparation method and application. A small molecule and monomer B copolymerizable macromer backbone is formed a small molecule monomers A, the side chain of a comb-graft copolymer of the macromonomer B; B is the weight of the macromonomer comb-shaped ground 0.1wt% ~ 80wt% of the mass of the graft copolymer, the weight of the monomer a small molecule is 99.9wt% ~ 20wt% of the comb-graft copolymer mass. The present invention is a comb copolymer is a graft copolymer containing pendant reactive groups can be used as compatibilizers, chain extenders.
