Abstract
PURPOSE: To reduce the halogen content and to prevent a metal mold, etc. from rusting, by contacting a halogen-containing olefin polymer obtained by use of a catalyst containing a halogen-containing magnesium solid, etc., with an organic carbonate.
CONSTITUTION: A halogen-containing olefin polymer obtained by use of a catalyst, composed of a halogen-containing magnesium solid, a titanium compound, an electron donor and an organometallic compound, and usually 0.005W5pts.wt., preferably 0.01W2pts.wt., for 100pts.wt. of said polymer of an organic carbonate, are molten and kneaded at a temperature ≥ the melting point of the polymer, preferably at about 170W300°C, by means of an extruder, Banbury mixer, etc. The organic carbonate is preferably dimethyl, diethyl, dipropyl, diphenyl, ethylene, propylene carbonate, etc.
