NOVEL ETHYLENE/ALPHA-OLEFIN COPOLYMER |
摘要 |
A copolymer of 30-90 mol % ethylene und an alpha-olefine having 3 to 14 carbon atoms, with a number average molecular weight of 300-30000, a Q value of not more than 3 and a Z value of 15-200, is prepared in a continuous way in the presence of hydrogen and of a vanadium compound with the formula VO(OR<1>)n X<1>3-n or VX<1>4 [R<1>: aliphatic hydrocarbon group having 1 to 20 carbon atoms; X<1>: halogen atom; n: number from 0 to 3] and an organo-aluminium compound with the formula R<2>mAl X<2>3-m [R<2>: aliphatic hydrocarbon group having 1 to 6 carbon atoms; X<2>: halogen atom; m: number from 1 to 3]. The copolymer is used as a synthetic lubricant oil or fuel oil component. |
