摘要

合成了一种含4,4′-二羟基苯甲酮的聚苯基膦酸盐作为阻燃剂。然而，杂质被检测到，并可能损害其性能和热稳定性。因此，提出了一种以水和己烷回流萃取为基础的纯化路线。结果表明，在不破坏聚合物的情况下，成功地去除杂质，特别是P-Cl基团。

Preparation and Purification of a Flame-Retardant Polyphenylphosphonate Containing 4,4'-Dihydroxybenzophenone

A polyphenylphosphonate containing 4,4'-dihydroxybenzophenone was synthesized as a flame retardant. However, impurities were detected and may compromise its properties and thermal stability. Thus, a purification route based on water and hexane extraction with reflux was proposed. Results showed success in removing impurities, especially P–Cl groups, without damaging the polymer.
