Abstract
A method of effecting polymerization of olefins having 6 or more carbon atoms or mixtures of such olefins (hereinafter referred to as the feed olefin), to produce a hydrocarbon liquid polymer which comprises mixing a catalyst composed of aluminum chloride, ketone having 4 or more carbon atoms and olefin catalyst constituent with 0.01 to 0.3 mole of ester, ether or alcohol per mole of said aluminum chloride and effecting the polymerization of the feed olefin at a reaction temperature of more than 60.degree.C.
Claims14
A method of polymerizing feed olefins having at least 6 carbon atoms or mixtures of such feed olefins, to produce a hydrocarbon liquid polymer, which comprises:
- polymerizing said feed olefin at a temperature of more than 60.degree.C, in contact with a catalyst prepared by reacting at a temperature of more than 60.degree.C, catalyst constituents consisting essentially of (a) aluminum chloride, (b) ketone having at least 4 carbon atoms, (c) olefin catalyst constituent selected from the group consisting of said feed olefin and olefins of lower carbon atom number, and (d) ester, ether or alcohol, the amount of (a) being from 0.1 to 5 mole percent based on the feed olefin, the molar ratio of (a)/(b) being from 1/1 to 1/1.2, the amount of (c) being more than 1 mole percent based on (a) and the amount of (d) being from 0.01 to 0.3 mole per mole of (a).
