Title:
METHOD FOR PREPARING DIENE-BASED GRAFT COPOLYMER RESIN, AND DIENE-BASED GRAFT COPOLYMER RESIN
Document Type and Number:
WIPO Patent Application WO/2021/075779
Kind Code:
A1
Abstract:
The present invention relates to a method for preparing a diene-based graft copolymer resin, and a diene-based graft copolymer resin prepared thereby, the method comprising the steps of: preparing a first reactant by mixing an aromatic vinyl-based monomer, a diene-based rubber polymer and a polymerization initiator; preparing a second reactant by mixing a vinyl cyanide-based monomer and an antioxidant; injecting the first reactant and the second reactant into a polymerization reactor and polymerizing same, thereby preparing a polymer; and removing unreacted monomers from a devolatilization tank.
