METHOD OF PREPARING FILM-FORMING AGENT Russian patent published in 1999 - IPC

Abstract RU 2140427 C1

FIELD: chemistry of polymers. SUBSTANCE: described is method of preparing film-forming agent by oligomerization of piperylene- containing fraction at elevated temperature and pressure in the presence of amylenes and titanium-containing catalyst followed by degassing, deactivation of oligomerizate by treatment with propylene oxide and dilution of oligomerizate with hydrocarbon solvent. Prior to deactivation, oligomerizate is treated with dicyclopentadiene in amount of 0.5-5 wt % based on oligomerizate. EFFECT: film-forming agent with relatively high drying time and low bending elasticity. 2 cl, 6 ex, 2 tbl
