METHOD OF PREPARING RUBBER-REINFORCED VINYL AROMATIC COPOLYMERS, AND VINYL AROMATIC COPOLYMERS

摘要

chemistry of polymers. SUBSTANCE: described is method of preparing rubber-reinforced vinyl aromatic copolymers. Method comprises (a) dissolving diene rubber (i) and/or linear block elastomer comprising at least unit of vinyl aromatic monomer and unit of conjugated 1,3- diene (ii) in mixture comprising at least one vinyl aromatic monomer and couple of solvents consisting of polar solvent and nonpolar solvent; and (b) polymerizing the solution thus prepared, optionally in the presence of initiator. Also described are vinyl aromatic copolymers. EFFECT: rubber- reinforced copolymers having superb physico-mechanical properties and good gloss. 9 cl, 5 ex, 1 tbl
