刚性高分子量聚芳醚腈的合成研究

Studies on Synthesis of Rigid-rigid High Molecular Weight Poly(cyanoarylether)

该文以２，６二氟苯甲腈和间苯二酚为原料，利用溶液高温缩聚制备聚芳醚腈［Ｐｏｌｙ（ｃｙａｎｏａｒｙｌｅｔｈｅｒ）ＰＣＥ］．同时，用ＩＲ对ＰＣＥ分子结构进行了表征；还用ＤＳＣ进行了聚合物的热性能测定．讨论了反应温度、碱的种类、聚合物的浓度、反应时间，以及水对合成的影响．结果表明，在Ｎ甲基吡咯烷酮溶液中，温度在２００℃时聚合４ｈ，同时加入一定量的水，得到的高聚物具有高分子量和耐高温性能．

:A kind of (poly(cyanoarylether) PCE) of high molecular weight could be prepared by the solution polycondensation of 2,6-propenties of PCE were studied by IR,DSC.We mainly discussed how to affact reaction's temperature,base,polymer's concentration,reaction's time and water in the paper.The result show that the PCE,which has high molecular weight and the heat resisting quality,was synthesized through adding a little water in Nmethylpyrrolidene.
