METHOD OF TREATMENT OF COPOLYMERS OF VINYLAROMATIC COMPOUNDS AND CONJUGATED DIENES

摘要

FIELD: chemistry of polymers. SUBSTANCE: claimed invention is concerned with method for treating copolymers with polycarboxylic acid cyclic anhydride. Such copolymers are formed at copolymerization initiation stage using alkaline metal (Me) based catalysts and subjected to deactivation so that they have end group of alkaline metal alcoholate (O- Me). EFFECT: more efficient treatment method.
