Abstract

The invention relates to the field of nucleating agents, and particularly discloses a PET nucleating agent composition and application thereof. The PET nucleating agent composition comprises the following components in parts by mass: 50-70 parts of a nucleating component and 30-50 parts of a plasticizing component, the nucleating component is a carboxylated cyclodextrin-crystal whisker compound; the carboxylated cyclodextrin-whisker compound is prepared by the following steps: grafting an inorganic salt whisker with a hyperbranched polymer, and reacting with carboxylated cyclodextrin, the plasticizing component comprises polyethylene glycol and phthalate in a mass ratio of (2-5): 1. The PET nucleating agent composition disclosed by the invention has the advantages of high crystallization rate and good crystallization effect.
