摘要： 1. A PROCESS FOR PREPARING IMPACT-RESISTANT POLYMERIC COMPOSITIONS COMPRISING GRAFT POLYMERIZING AT LEAST ONE ETHYLENICALLY UNSATURATED MONOMER SELECTED FROM THE GOUP CONSISTING OF STYRENES, ACRYLONITRILE, METHACRYLONITRILE, STYRENE/ACRYLONITRILE MIXTURES, ALKYL ACRYLATES, ALKYL METHACRYALTES, VINYL CHLORIDE AND VINYL ACETATE ONTO AN ELASTOMER SELECTED FROM THE GROUP CONSISTING OF SATURATED COPOLYMERS OF ETHYLENE AND AN A-OLEFIN AND LOW UNSATURATION COPOLYMERS OF ETHYLENE, AND A-OLEFIN AND A DIENE OR POLYENE HYDROCARBON, WHEREIN SAID ELASTOMER IS DISSOLVED IN A SOLVENT SELECTED FROM THE GROUP CONSISTING OF N-BUTANE, PROPANE AND MIXTURES THEREOF.
