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 a carboxylic anhydride.
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, is catalytically treated with usually 0.005W5pts.wt., preferably 0.01W2pts.wt., for 100pts.wt. of said polymer, of a carboxylic anhydride such as oleic, palmitic, stearic, or malonic anhydride, to reduce the halogen content of said polymer. The addition of 0.05W10mol of an 8W30C fatty acid or its metal salt to 1mol of the carboxylic anhydride, makes it possible to decrease the amount of the carboxylic anhydride to be used.
