Document Type and Number:
WIPO Patent Application WO/2019/059664
Kind Code:
A1
Abstract:
The present invention relates to a method for preparing a graft copolymer, the method comprising the steps of: 1) introducing a conjugated diene-based monomer, followed by polymerization, to prepare a conjugated diene-based polymer; and 2) introducing the conjugated diene-based polymer, an aromatic vinyl-based monomer, and a vinyl cyanide-based monomer, followed by polymerization, to prepare a graft copolymer, wherein an emulsifier having an APHA color of 50 or less and a critical micelle concentration of 1-50 g/ℓ is introduced, to a graft copolymer, and a thermoplastic resin molded product, and specifically, to a method for preparing a graft copolymer having excellent polymerization stability, color, light resistance, and surface clearness, to a graft copolymer, and to a thermoplastic resin molded product.
