GRAFT COPOLYMER, METHOD FOR PREPARING THE SAME AND THERMOPLASTIC RESIN COMPOSITION CONTAINING THE SAME

摘要

PURPOSE: A graft copolymer, a manufacturing method thereof, and a thermoplastic resin composition containing thereof are provided to easily manufacture the graft copolymer with large diameter. CONSTITUTION: A manufacturing method of a graft copolymer comprises the following steps: producing polymer latex seeds with the index of refraction over 1.5 and the average diameter of 150~300 nanometers by adding a cationic emulsifier during the polymerization of a polymer latex; producing a large-sized composite rubber polymer core with the average diameter of 300~600 nanometers by adding an alkyl acrylate monomer, a cross-linking agent, and a grafting agent to the polymer latex seeds; and manufacturing the graft copolymer by graft polymerizing under the presence the core.
