The Synthesis and Characterization of Epoxy terminated Phenolphthalein Poly(cyanoarylether)

环氧树脂（ＥＲ）的冲击韧性和耐开裂性较差，因此，提高其抗冲强度而不显著影响力学性能和耐热性能是重要的研究课题．对于ＥＲ的增韧，以前主要采用液态橡胶．近年来，人们开始研究使用高性能热塑性树脂增韧ＥＲ［１～３］．聚醚腈（ＰＣＥ）是目前机械强度最高的热塑性...

Epoxy terminated poly(cyanoarylether)(E PCE) with M n from 1 000 to 12 000 were synthesized by the reaction of epichlorohydrin with PCE oligomer with —OK terminal groups prepared by condensation of phenolphthalein (PPH) with 2,6 dichlorobenzonitrile (DCBN) using K 2CO 3 as catalyst. The E PCEs were characterized by IR and 1H NMR spectra, the solubility of E PCE samples was also measured. In addition, the solidification action and the heat resisting quality of the fully crosslinked E PCE/DDS were also measured by DSC and TGA.
