METHOD FOR PRODUCING MOLDING COMPOSITION AND METHOD FOR PRODUCING MOLDED PRODUCT

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a molding composition capable of eliminating melt fracture, which occurs at the start of molding, in a short period of time even when a melt processable polymer such as polyolefin is extrusion-molded at a high speed.SOLUTION: The method for producing a molding composition comprises steps of: preparing a mixture (A) comprising a perfluoro elastomer and a melt-processable resin; preparing a mixture (B) comprising an ethylene/tetrafluoroethylene copolymer and a melt processable resin; and mixing the prepared mixture (A) and mixture (B).SELECTED DRAWING: None
