METHOD OF PREPARING FILM-FORMING AGENT

摘要

FIELD: chemistry of polymers. SUBSTANCE: film-forming agent is prepared by radical copolymerization in body of propylene, C4- unsaturated and C4-acetylenic hydrocarbons include top product of stripping tower where dimethylformamide is regenerated to recover butadiene from ethylene production pyrolysis product, weight ratio of components being as follows, wt %: top product of stripping tower where dimethylformamide is regenerated to recover butadiene from ethylene production pyrolysis product, 20-40; piperylene, 60-80. EFFECT: wider range of raw stock to prepare film-forming agent and improved properties thereof. 2 cl, 3 ex, 2 tbl
