摘　　要：采用全氟烷基乙烯基醚（PAVE）,包括全氟甲基乙烯基醚（PMVE）、全氟乙基乙烯基醚（PEVE）和全氟丙基乙烯基醚（PPVE）对聚全氟乙丙烯（FEP）进行改性,对比了改性树脂的各项性能。结果表明,改性树脂的临界剪切速率提高了2~3倍,四氟乙烯（TFE）-六氟丙烯（HFP）-PEVE共聚物的挤出速率能达900 m/min。PEVE改性FEP树脂的临界剪切速率、抗挠寿命、高温拉伸强度和挤出速率均比PPVE优异。Using perfluoroalkyl vinyl ethers(PAVE), including perfluoromethyl vinyl ether(PMVE), perfluoroethyl vinyl ether(PEVE),and perfluoropropyl vinyl ether(PPVE) modified fluorinated ethylene-propylene(FEP), compared the performance of the modified resin. The results showed that the critical shear rate improved 2 ~3 times, the extrusion rate of tetrafluoroethylene(TFE)-hexafuoropropylene(HFP)-PEVE copolymer could reach 900m/min. The critical shear rate, flex life, high-temperture tensile strength and extrusion of the FEP resin modified by PEVE was excellent than PPVE.
