    摘要: The present invention provides a processing aid for polyolefins which can eliminate melt fracture occurring at the start of molding in a short time even when a polyolefin, which is a melt-processable polymer, is extrusion-molded at a high speed. The present invention also aims to provide a polyolefin composition containing such a processing aid for polyolefins and a polyolefin. The processing aid for polyolefins contains an ethylene/tetrafluoroethylene copolymer as the only fluoropolymer, the ethylene/tetrafluoroethylene copolymer having a melting point of 170°C to 270°C.
