A METHODS FOR PREPARING VINYLCYAN COMPOUND-CONJUGATED DIENE RUBBER-AROMATIC VINYL COMPOUND GRAFT COPOLYMER, METHODS FOR THERMOPLASTIC RESIN COMPOSITIN COMPRISING THE SAME, AND THERMOPLASTIC RESIN COMPOSITION

摘要

The present invention relates to a method for preparing a vinyl cyanide compound-conjugated diene rubber-aromatic vinyl compound graft copolymer, a method for preparing a thermoplastic resin composition comprising the same, and a thermoplastic resin composition, and more particularly, to a conjugated diene rubber latex polymerization during polymerization The enlarged conjugated diene-based rubber latex, in which the diene compound and molecular weight regulator are divided, the content of the emulsifier is reduced, the gel content is lowered by using a specific electrolyte, and is enlarged with an acid thickening agent, has a wider particle diameter at half maximum, so the appearance of gloss and reflective haze, etc. Properties and impact resistance are improved, and there is an effect of reducing injection residues during injection molding.
