(57) [Summary] [Object] DBSs that have solved the problem of stability, and a novel and useful polyolefin-based resin composition that is excellent in transparency and that has significantly suppressed odor during molding and in final molded articles Suggest. [Structure] Dibenzylidene sorbitol (DBS) 10 0.01 to 50 parts by weight of an alkali metal salt of an amino acid and a peptide comprising the same (compound A) and a compound containing an alcoholic hydroxyl group (aliphatic alcohol and its alkylene oxide adduct, phenolic alkylene oxide 1 to 100 parts by weight of an adduct, a partial ester of a polyhydric alcohol and its alkylene oxide adduct, hydrogenated castor oil and its alkylene oxide adduct, hydroxyalkylamine and hydroxyalkylamide) are added to form a composition. DBS obtained in this way The system composition is useful as a nucleating agent for a polyolefin-based resin, and forms a polyolefin-based resin composition having predetermined characteristics by applying the nucleating agent composition. |
