METHOD FOR PREPARING ACRYLONITRILE-BUTADIENE-STYRENE GRAFT COPOLYMER, AND ACRYLONITRILE-BUTADIENE-STYRENE THERMOPLASTIC RESIN CONTAINING SAME

摘要

The present invention relates to a method for preparing an acrylonitrile-butadiene-styrene graft copolymer with improved impact strength, an acrylonitrile-butadiene-styrene graft copolymer prepared by the method, and an acrylonitrile-butadiene-styrene thermoplastic resin containing the same, the method comprising the steps of: (step 1) preparing a diene-based rubber latex by adding an acrylate-based cross-linking agent; and (step 2) carrying out graft copolymerization by injecting a cross-linking agent, which is identical with the acrylate-based cross-linking agent, an aromatic vinyl-based compound and a cyanovinyl-based compound into the diene-based rubber latex.
