Granular nucleating agent composition and polyolefin resin composition comprising the same

摘要: PROBLEM TO BE SOLVED: To obtain a composition allowing excellent dispersion of nucleating agent in polyolefin resin thereby improving rigidity resultant by admixing specific ratio agent, metal soap and binder comprising an organic compound having lower melting point than the high-speed solid mixer equipped with rotating blade softening resulting granulation admixture. SOLUTION: A (A) is selected from salts phosphate ester formula I (wherein R1 R2 are each H or 1-9C alkyl; M alkali metal) II R3 R4 1=5C alkylidene; aromatic carboxylic acids III R5 H, alkyl alkoxyl; Al; (n) valence number). As (B), employed salt 8-22C fatty acid, like. (C) 200 deg.C below. The components A, B C compounded amount 100 pts.wt., 10-100 pts.wt. at least 10 respectively.
