The purpose of the present invention is to provide a polyolefin composition comprising: a processing aid for polyolefins, which enables the avoidance of melt fracture, which occurs at the beginning of molding, within a short period of time even when a polyolefin that is a melt-processable polymer is extrusion-molded at a high speed; and a specific polyolefin.nThe present invention is a processing aid for polyolefins, which is characterized by comprising a perfluoro elastomer, and which can be used for the extrusion molding of at least one polyolefin selected from the group consisting of a low-density polyethylene, a linear low-density polyethylene, a high-density polyethylene, a metallocene-catalyst-type linear low-density polyethylene, polypropylene and polyvinyl chloride. |
