DIENE (CO)POLYMER HYDROGENATION PROCESS Russian patent published in 1999 - IPC

Abstract RU 2136699 C1

FIELD: rubber industry. SUBSTANCE: invention relates to hydrogenation of carbo-chain polymers and can be used for production of rubber products applied in various areas. Diene (co)polymers are treated with hydrogen in hydrocarbon solvent in presence of catalytic system consisting of nickel compounds, trialkylaluminum, and a modifying additive, in particular, compound of formula (RCOO)3Fe wherein R is C5-C16-alkyl at molar ratio nickel/modifier/trialkylaluminum (0.1-0.9):90.9-0.1):(3-6) and amount of nickel 0.01 to 0.5% of unsaturated (co)polymer weight. EFFECT: increased degree of hydrogenation and simplified removal of catalyst from product. 1 tbl, 11 ex
