摘　　要：聚芳醚砜(PES)作为综合性能优良的工程塑料,近年来得到广泛的应用。本文研究了聚合时间、聚合温度、反应物配比对聚芳醚砜产量和分子量的影响,在双酚S/双氯/NaOH摩尔比为1∶1∶2.48、脱水时间2 h、聚合温度230℃、聚合时间8 h的条件下,制备了—OH封端的聚芳醚砜。Polyaryl ether sulfone(PES)with high-performance has been used as engineering plastics more and more widely.In this paper,the effect of reaction time,temperature and the ratio of reactents was studied.PES with—OH as end group were synthesized when the molar ratio of bisphenol S,bisphenol Cl and NaOH was 1∶1∶2.48,reacted at 110 ℃ for 2 h,then polymerized at 230 ℃ for 8 h.
