METHOD OF PRODUCING PETROLEUM POLYMERIC RESIN Russian patent published in 1998 - IPC

FIELD: chemical industry, more particularly production of para, paint materials, and rubbers. SUBSTANCE: present invention describes method for producing petroleum polymeric resin by polymerization of unsaturated compounds of polycondensate fractions at 30-130 in the presence of 1-4 wt % of mixture of diethylaluminium chloride and production waste resulting from microspherical polypropylene polymerization catalyst at weight ratio of (0.1-10.0): 1.0, respectively. Production waste represents mixture comprising, wt.- %: titanium chloride-aluminium chloride, 15; diisoamyl ether, 21; and heptene, 54. EFFECT: more efficient production method. 3 tbl
