ABSTRACT:
Disclosed is a method for removing an aluminum halide or its complex catalyst from a polymerization product comprising the steps of adding to the polymerization product an aprotic polar solvent in an amount of 1.0 through 6.0 mol per one mol of the aluminum halide in the catalyst present in the product and sufficiently mixing them at a temperature of 70.degree. through 150.degree. C, and then, filtering the mixture at a temperature of 70.degree. through 150.degree. C. The addition of the aprotic polar solvent remarkably facilitates the separation of the catalyst from the polymerization product.
