Functionalized elastomers blended with polar copolymers of styrene and acrylic acid methacrylic acid or maleic anhydride

摘要

Novel graft copolymer elastomers comprising a rubbery substrate polymer and a graft copolymer of a monomer capable of grafting to the rubbery substrate and a copolymerizable comonomer having pendant reactive groups capable of functionally reacting with reactive polar functionality of a copolymer of a monovinylidene aromatic monomer and a copolymerizable polar comonomer are disclosed.
