COMPOSITION OF THE INITIATOR OF FORMATION OF ACTIVE CENTERS CONTAINING SORBIT DIACETAL AND SORBIT TRIACETAL

摘要

The present invention provides a nucleator composition including sorbitol acetal, sorbitol diacetal, and sorbitol triacetal. The nucleator composition can improve the nucleation performance of a polymer, increase transparency, glossiness, flexural modulus and tensile strength of polymer films, polymer sheets and polymer moulding articles, and increase heat distortion temperature and dimensional stability of polymer articles.
