METHOD FOR PRODUCTION OF PETROLEUM POLYMER RESINS Russian patent published in 1997 - IPC

Abstract RU 2086569 C1

FIELD: production of petroleum polymer resins. SUBSTANCE: resins are prepared by polymerization of unsaturated compounds of fractions of liquid products of pyrolysis. The process is carried out at 30-130 C in the presence of aluminium powder and waste of production of microspherical catalyst of polymerization of propylene, weight ratio of Al:TICl₄ being (0.02-0.2): 1.0. Concentration of catalyst is 1-4 wt.-%. Waste comprises mixture which contains, wt. -%: titanium tetrachloride, 15; aluminium chloride, 10; diisoamyl ether, 21; and heptane, 54. EFFECT: improved efficiency. 3 tbl
