Liquid ethylene-type random copolymer, process for production thereof, and use thereof |
| abstract |
Abstract of the Disclosure: A liquid ethylene-type random copolymer, charac-terized in that (a) it has an ethylene unit content of 10 to 85 mole% and an alpha-olefin unit content of 15 to 90 mole%, (b) it has a low molecular weight, (c) it has a narrow molecular weight distribu-tion, (d) the dispersion of the ethylene units and alpha-olefin units in the polymer chain is in the advanced state, and (e) the directions of bonding of the alpha-olefin units in the polymer chain are nearly the same. The copolymer is prepared by copolymerizing ethylene and an alpha-olefin having 3 to 20 carbon atoms in the presence of a catalyst comprising a compound of a transition metal of Group IVb of the periodic table and an aluminoxane. The copolymer is very useful as a synthetic lubricant oil. |
