摘要： 通过分子设计, 成功合成了一种含有三苯基膦结构的二氟单体——4,4’-二氟二苯苯磷氧(BFPPO). 在碱催化条件下, BFPPO与2-双-(4-羟苯基)六氟丙烷(六氟双酚A)缩聚得到一种新型含三苯基膦结构的聚芳醚材料(6F-PAEPO). 使用FTIR，1H NMR, 31P NMR, 和16F NMR等表征手段确定了聚合物的结构, 聚合物表现出良好的热稳定性、有机可溶性、机械性能和光透过性能, 其中聚合物的玻璃化转变温度高达211℃, 空气气氛和氮气气氛下5%热失重温度分别为512℃和523℃, 聚合物薄膜的最大光透过率超过80%. 尤其, 聚合物由于主链中三苯基磷氧结构的存在, 表现出了优异的阻燃性能, 有限氧指数(LOI)达到39.9%.

Abstract: A novel fluorine-contained poly(arylene ether) containing phenylphosphine oxide (6F-PAEPO) was synthesized by the nucleophilic substitution between bis(4-chlorophenyl)phenyl phosphine oxide (BFPPO) and 4,4'-(Hexafluoroisopropylidene)diphenol (Bis AF). BFPPO was prepared from dichlorophenylphosphine oxide and 4-bromofluorobenzene through Grignard reaction. The structure of the polymer was confirmed by FTIR, 1H NMR, 31P NMR, and 16F NMR. The polymer exhibited excellent thermal stability, mechanical property and solubility. The glass transition temperature of 6F-PAEPO was 211℃, the temperature for 5% weight loss of 6F-PAEPO in N2 and air were 512 and 523℃, respectively. The maximum trasmittance of the polymer film is above of 80%. Especially, the polymer exhibited an outstanding flame retardancy property due to the existence of triphenylphosphine-oxide moities in the main chain. LOI of the polymer was up to 39.9%.
