摘要： A modified polymer rubber is obtained by
(1) graft-polymerizing at least one grafting monomer to a shredded rubbery polymer (A) in an aqueous suspension at a temperature of 30° - 130°C to obtain a graft polymer, and (2) kneading the graft polymer with at least one polymerizable monomer in the presence of a free radical initiator at a temperature of 180°-280°C. This process does not cause gel formation and is advantageous in manufacturing cost. The modified polymer rubber thus obtained is excellent in processability and storage stability, and highly useful as a compatibilizer for various resins.-
