Beschreibung
Zusammenfassung:	The present invention provides a processing aid for polyolefins capable of improving the processability in processing polyolefins at a temperature lower than 220° C. and a high shear rate. The processing aid for polyolefins is intended to be used in processing a polyolefin at a temperature lower than 220° C., and contains a fluoropolymer that includes a polymerized unit (a) based on CF2═CFCF3 and a polymerized unit, (b) based on at least one selected from the group consisting of monomers represented by CH2═CX11Y11 and monomers represented by CF2═CX21Y21.
