METHOD OF PREPARING VINYL AROMATIC RUBBER-REINFORCED POLYMERS

摘要

FIELD: chemical industry. SUBSTANCE: method comprises mixing first stream of first vinyl aromatic prepolymer containing rubber phase of fine particles resulting from ÉÅÅ type reactor with second stream consisting of prepolymer having larger particles resulting from continuous stream reactor with stirrer; executing polymerization until rubber reinforced vinyl aromatic polymer with bimodal morphology is obtained. EFFECT: significantly improved synergism and superior aesthetic properties of vinyl aromatic polymer. 7 cl, 3 dwg, 3 tbl
