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 cyan 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 compound and molecular weight during polymerization The thickened conjugated diene rubber, which was enlarged with an acid thickening agent after adding an electrolyte to lower the gel content of the conjugated diene rubber by reducing the emulsifier content by dividing the control agent, expands the full width at half maximum particle diameter, resulting in glossiness, reflective haze, and fluidity and improved impact resistance and reduced residues during injection molding.
