摘要

Nucleating agent for polyolefin resin having excellent β crystal forming action, nucleating agent composition for polyolefin resin containing the same, master batch for polyolefin resin, polyolefin resin composition, molded article thereof, film thereof, method for producing a porous film, and package is provided. The following general formula (1) (In the general formula (1), M represents a metal atom having a specific gravity of 1 to 3 valence of 4.0 or less, a represents 1 or 2, b represents 1 or 3, and x represents an integer of 1 to 3 and satisfies ax = 2b Z represents a group represented by the following general formula (2) or general formula (3). (In the general formulas (2) and (3), * represents a position connected to Z in the general formula (1), Y represents a direct bond or an alkylene group having 1 to 4 carbon atoms, and R 1 to R 10 each independently represent a hydrogen atom, a hydroxy group, a halogen atom, an alkyl group having 1 to 10 carbon atoms, etc.)).
