METHOD FOR PRODUCTION OF BLACK PETROLEUM POLYMER RESINS Russian patent published in 2000 - IPC

Abstract RU 2158276 C1

FIELD: polymer production. SUBSTANCE: black petroleum polymer resins suitable for production of general mechanical rubber goods and tyres are prepared under mild conditions from heavy oil pyrolysis tar with boiling range 190-360 C. For that, raw material is blown with air (15-30 h-1) at 130-160 C in presence of 0.01 to 0.5% of variable-valence metal salts with general formula (RCOO)nMe, wherein Me is Co, Ni, Mn, or Fe, n metal valence, and RCOO is acid residue of naphthenic, tall, synthetic fatty, colophony, vegetable and animal fatty acids. EFFECT: increased yield of resins. 3 tbl
