PROCESS FOR PREPARING SYNTHETIC FILM-FORMING SUBSTANCE

摘要

FIELD: production of synthetic film-forming agents. SUBSTANCE: method is carried out by cation copolymerization of cationophile monomers which are contained in technical piperylene or by their copolymerization with vinylaromatic hydrocarbons. Polymerizate is allowed to stand within 2-7 h before deactivation of catalyst takes place, mass ratio of catalyst and promoter being (1.5-12.0):1. EFFECT: decreases toxicity of desired product. 2 tbl
