摘要
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 polypiaenylene 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.
