摘要： A nucleating agent composition for increasing rigidity and toughness of polypropylene is provided. The nucleating agent composition comprises a carboxylate nucleating agent and a phosphate nucleating agent. The carboxylate nucleating agent is selected from the group consisting of sodium benzoate and hydroxyl aluminum para-tertiary butyl benzoate, and the phosphate nucleating agent is selected from any one of sodium 2,2′-methylene-di(4,6-di-t-butyl phenyl) phosphate and aluminum bis[2,2′-methylene-di(4,6-di-t-butylphenyl)] phosphate. The nucleating agent composition according to the present invention not only can significantly improve the bending modulus and thermal deformation temperature of polypropylene, but also can improve the impact strength of polypropylene.
