摘要

The purpose of the present invention is to provide a metal salt of an alicyclic dicarboxylic acid which has excellent dispersibility in polyolefin resins, and is thus excellent in crystallinity improving effect that is essential performance as a crystal nucleating agent for polyolefin resins, regardless of processing conditions; a method for producing the metal salt of an alicyclic dicarboxylic acid; a crystal nucleating agent containing the metal salt of an alicyclic dicarboxylic acid; a crystal nucleating agent composition for polyolefin resins containing the crystal nucleating agent and a fatty acid metal sa a polyolefin resin composition containing the crystal nucleating agent; and a polyolefin resin molded article obtained using the polyolefin resin composition as a raw material. Provided is a metal salt of an alicyclic dicarboxylic acid in which the alicyclic dicarboxylic acid is an alkyl substituent-containing cyclohexane-1,2-dicarboxylic acid, and the metal salt is a calcium salt, a hydroxyaluminum salt, a disodium salt, or a dilithium salt.
