HPPD与芳基二氯磷酸酯的相转移反应及其性能研究

Phasetransfer Reaction of HPPD and Aryl Phosphorodichloridates and Study of Property

阻燃剂低聚磷酸酯由Ｎ，Ｎ’—二（对羟基苯基）均苯四甲酸双亚胺（ＨＰＰＤ）与芳基二氯磷酸酯经相转移催化缩聚而成．该聚合物由ＩＲ、１Ｈ、１３Ｃ、３１Ｐｎ，ｍ，ｒ证实，分子量由３１Ｐｎ，ｍ，ｒ对未端基团分析数据决定，热稳定性和阻燃性由重量分析法（ＴＧ）和极限氧指数测定仪（ＬＯＩ）分析确定．

The flame rstardant polyphospyate esters were synthesized by phase transfer catalysis polyconden station of N,N' his (P-hydroxy phenyl)pyromellitic diimide with aryl phosphoro dichloridates. The polymers were Characteriled by i. r. and 1H,13C and 31Pn,m,rspectroscopy. The molecular weights were determined by end group analysis using31Pn,m,r spectral date.The thermal stabity and flammability of the polymers were analysed by thermogravimety and limiting Oxygen index(LOI) respectively.
