Method for preparing acrylonitrile-butadiene-styrene graft copolymer and acrylonitrile-butadiene-styrene thermoplastic resin comprising the same
First Claim
1. A method for preparing an acrylonitrile-butadiene-styrene graft copolymer, which comprises:
- a first step of preparing a diene-based rubber latex by adding an acrylate-based cross-linking agent; and
a second step of inserting the acrylate-based cross-linking agent, an aromatic vinyl-based compound and a vinyl cyan-based compound into the diene-based rubber latex and subsequently performing graft copolymerization,wherein the acrylate-based cross-linking agent is (propylene glycol)n diacrylate, in which n is an integer of 1 to 15.

Abstract
The present invention relates to a method for preparing an acrylonitrile-butadiene-styrene graft copolymer having improved impact strength, which comprises: a step of preparing diene-based rubber latex by adding an acrylate-based cross-linking agent (Step 1); and a step of inserting the same cross-linking agent with the acrylate-based cross-linking agent, an aromatic vinyl-based compound and a vinyl cyan-based compound to the diene-based rubber latex and then subjecting thereof to graft copolymerization (Step 2), an acrylonitrile-butadiene-styrene graft copolymer prepared by the method, and an acrylonitrile-butadiene-styrene thermoplastic resin comprising the same.
