Abstract

Abstract: Spirocylic pentaerythritol phosphate ester, a kind of intumescent flame retardant, has good compatibility with the polypropylene and excellent flame retardant on PP. However the correlation between the space structures of the intumescent flame retardant and polypropylene has not been revealed. In this paper crystal diffraction of spirocyclic pentaerythritol phenol ester of phosphoric acid are used to study its structure features and the results show that the phenol ester crystal is orthorhombic, Pna21 space group, and there are two six-member rings linked to the same atom which belongs to similar chair conformation forming a stable spiro structure and an irregular axisymmetric structure, and none weak hydrogen bonds exists in the system.
