PROCESS FOR PREPARING PETROLEUM POLYMERIC RESIN Russian patent published in 1994 - IPC

Abstract RU 2024552 C1

FIELD: a process for manufacturing film-forming materials. SUBSTANCE: in order to simplify the process and increase the resin softening temperature, the oligomerization of an industrial styrene-containing fraction is carried out in a hydrocarbon solvent in the presence of titanium tetrachloride and a mixture of oxygen-containing promoters selected from the groups consisting of phenol, C4-C24-ester as well as water, ketone, aldehyde, C3-C11- peroxide and or hydroperoxide at a phenol to ester to water + carbonyl + peroxide compounds molar ratio of 1:0.1-2.0:0.05-0.20. EFFECT: greater efficiency of the process. 2 cl, 2 tbl
