Abstract:
Polyphenylphosphonic acid diphenyl sulfone ester (PSPPP) polymer with number average molecular weight over 104 was synthesized by Melt Polycondensation using Bisphenol S and phenylphosphonic acid dichloride as raw materials, the influence of reaction conditions and other factors on the molecular weight of the polycondensate. The structure of the polymer was characterized by IR, elemental analysis and NMR. The thermal properties of PSPPP and the flame retardancy of polyethylene terephthalate (PET) were measured by thermal analysis instrument and oxygen index instrument. The research shows that PSPPP has high thermal stability and excellent flame retardant effect on PET .Key words:

Abstract:
The invention relates to the technical field of flame retardant polymer materials, and provides a polycarbonate/polyphenylphosphonic acid diphenyl sulfone Ester flame retardant material and a preparation method thereof. In this method, the polycarbonate oligomer is synthesized by using bisphenol A and diphenyl carbonate as raw materials, and then the polyphenylphosphonic acid diphenyl sulfone Ester oligomer is synthesized by using phenylphosphonyl dichloride and Bisphenol S as raw materials, polycarbonate/polyphenylphosphonic acid diphenyl sulfone Ester flame retardant materials were prepared by block copolymerization of polycarbonate oligomer and polyphenylphosphonic acid diphenyl sulfone Ester oligomer. In the preparation method of the invention, polyphenylphosphonic acid diphenyl sulfone Ester is used as a reactive flame retardant, which overcomes the unsatisfactory flame retardant effect caused by the uneven dispersion of the additive flame retardant in polycarbonate, and the problem of the decrease of mechanical properties due to the poor compatibility of the interface.Last Update：2023-08-16 22:09:08

Abstract:
Toxicity Study of polyphenylphosphonic diphenyl sulfone Ester Wang Yuzhong (Department of Chemistry, Sichuan Union University, Chengdu 610064) Xia Yan Zhi Zhong Jin Yi Ding Yufang (Qingdao University, Qingdao 266033) our previous studies have shown that [1,2] polyphenylphosphonic acid diphenyl sulfone Ester is an ideal flame retardant for polyethylene terephthalate. This flame retardant can be practical, but also depends on its safety to the human body...
