Abstract

The present invention relates to a method for preparing a thermoplastic resin composition having remarkable surface clearness and gloss and capable of preventing mold deposits during a high speed injection process by: preparing a resin latex by using a reactive emulsifier during emulsification polymerization of a rubber latex comprising polybutadiene and using a hydrophobic initiator during graft copolymerization of the rubber latex an aromatic vinyl monomer and a vinyl cyano monomer; aggregating the resin latex; compression hydrating the same to have a water content of less than 10% by using a compression dehydrator; and carrying out a wet powder extrusion process. The method comprises: (1) a rubber latex preparation step of preparing a rubber latex from a conjugated diene monomer by using a reactive emulsifier; (2) a resin latex preparation step of preparing a resin latex by graft copolymerizing an aromatic vinyl monomer and a vinyl cyano monomer to the rubber latex by using a reactive emulsifier and a hydrophobic initiator; (3) a dehydration step of aggregating the resin latex and obtaining a wet powder by mechanically dehydrating the aggregated product to have a water content of 2 15%; and (4) a wet coextrusion step of preparing a pellet by wet coextruding the wet powder with an aromatic vinyl vinyl cyano copolymer.
