Abstract

PURPOSE: To prevent deterioration and denaturation of a polyolefin due to the presence of a halogen, by treating the polyolefin obtained by use of a halogen- containing catalyst with a specified compound in the absence of water.
CONSTITUTION: To a polyolefin, such as PE or PP, obtained by polymerizing a monomer by use of a halogen-containing catalyst consisting of a halide of a transition metal such as Ti or V, and an organometallic compound such as alkylaluminum halide is added 0.1W200mol times the quantity of the halogen in the polyolefin, of a compound having a structure of the formula, e.g., acetic anhydride. Then, the mixture is treated at a temperature ≥30°C and lower than the m.p. of the polyolefin for 1minW5hr in the absence of water.
