Abstract
A method of preparing an olefin oligomer by polymerizing an olefin having 6 or more carbon atoms, wherein said olefin is polymerized in the presence of a catalyst consisting of (a) a polyhydric alcohol derivative obtained by replacing the hydrogen atoms of all the hydroxyl groups of the polyhydric alcohol by either acyl groups exclusively or by acyl groups and alkyl groups, both of said groups having 1 - 20 carbon atoms, (b) an aluminum halide in an amount of 1.1 - 2.8 mole per one ester bond or ether bond possessed by said polyhydric alcohol derivative and (c) metallic aluminum powder.
Claims6
A method or preparing an olefin oligomer, which comprises polymerizing at a temperature of from 50.degree. to 150.degree. C, an olefin or a mixture of olefins having 6 or more carbon atoms, in the presence of a catalyst mixture of (a) a polyhydric alcohol derivative obtained by replacing the hydrogen atoms of all the hydroxyl groups of the polyhydric alcohol by either acyl groups exclusively or by acyl groups and alkyl groups, both of said groups having 1 to 20 carbon atoms, (b) an aluminum halide in an amount of 1.1 to 2.8 mole per one ester bond or ether bond of said polyhydric alcohol derivative, and (c) metallic aluminum powder;
- and recovering an olefin oligomer from the polymerization reaction mixture.
