利用再分配反应制备了双端带有羟基的低分子量聚苯醚(PPO-LMW)，并将PPO-LMW作为环氧树脂(EP)的固化剂参与固化反应。在此基础上，对EP/PPO-LMW体系的相容性及性能进行了研究。结果表明，通过再分配反应制得的双端带有羟基的PPO-LMW与EP具有良好的相容性，EP/PPO-LMW体系固化物的相态均一。加入PPO-LMW以后，EP的冲击性能、介电性能及热稳定性得到了明显的改善。

Low molecular weight polyphenylene oxide (PPO-LMW)with two hydroxyl end groups was prepared by redistribution reaction,and was used as curing agent of epoxy (EP) resin. The compatibility and properties of EP/PPO-LMW system was further studied. The results show that the compatibility between EP and PPO-LMW with two hydroxyl end groups is good. Cured EP/PPO-LMW system show homogenous phase.After addition of PPO-LMW into epoxy,the impact resistance,dielectric properties and thermal stability of cured EP/PPO-LMW system are greatly improved.
