ABSTRACT:
A method of preparing a polyolefin oil in the present invention comprises polymerizing an olefin having 6 or more carbon atoms in the presence of a catalyst mixture consisting of a polyester of polycarboxylic acid and an aluminum halide. The thus prepared polyolefin oil has a low viscosity and a high viscosity index. When the foregoing polymerization is effected by adding aluminum powder to said catalyst mixture, the content of halogen in the resulting polyolefin oil can be decreased all the more.
