PURPOSE:To enable to perform effectively and stably substitution, by substituting polyolefin resin C for resin B by supplying the polyolefin resin C after the resin B has been substituted for ethylene-alpha,beta-unsaturated carboxylic acid or its anhydride copolymer resin or its metallic neutralized article A by supplying ethylene-alpha,beta-unsaturated carborylic acid ester copolymer resin B. CONSTITUTION:As the titled method is to substitute polyolefin resin C for resin B by supplying the polyolefin resin C after the resin B is substituted for resin A by supplying ethylene-alpha,beta-unsaturated carboxylic acid ester copolymer resin B, in a method substituting the polyolefin resin C for ethylene-alpha,beta-unsaturated carboxylic acid or its anhydride copolymer resin or its metallic neutralized article A sojourning within an extrusion molding equipment, it is capable of making substitution of the polyolefin resin C complete in a short period of time under a state wherein mixing of gel based on the resin A with a polyolefin-resin-molded article could by controlled extremely low. |
