Method of preparing thermoplastic resin composition having superior surface clearness and gloss

Abstract

Disclosed are a method of preparing a thermoplastic resin composition having superior surface clearness and gloss. More particularly, the present invention relates to a method of preparing a superior thermoplastic resin composition which has superior surface clearness and superior gloss and may prevent mold deposition during a high speed injection process, by using a reactive emulsifier during emulsion polymerization of rubber latex composed of polybutadiene, preparing resin latex using a hydrophobic initiator during graft copolymerization of rubber latex, an aromatic vinyl monomer, and a vinyl cyan monomer, compression dehydrating a moisture content to less than 10% using a compression type dehydrator after agglomerating the resin latex, and performing a wet powder extrusion process.
