摘要： 由酚酞和4,4′-二氯二苯酮经亲核缩聚制得了一系列不同分子量的含—OK端基的聚醚酮低聚物,将其与环氧氯丙烷反应得到了分子量为1000～8000的含环氧端基聚芳醚酮(E-PEK)。用IR和1HNMR表征了E-PEK的分子链结构,测定了Tg、溶解性和熔融粘度。研究了E-PEK/DDE体系的固化,固化后树脂的Tg∞=183～215℃,与低聚物的初始分子量有关。

Abstract: Epoxy-terminated phenolphthalein polyaryletherketones (E-PEK) of Mn=1000～8000 were synthesized by reaction of epichhlorohydrin with PEK oligomer having-OK terminal groups prepared by condensation of phenolphthalein (PPH) with 4,4'-dichlorobenzophenone (DCBP) at molar ratios of PPH to DCBP from 1:0.5 to 1:0.9. The E-PEKs were characterized by IR and 1HNMR spectra,initial glass transtion temperature (Tgi); the melting viscosity and solubility of E-PEK samples were also measured. The E-PEKs were cured with 4, 4'-diaminodiphenylether (DDE) and the glass transition temperatures of the fully erosslinked E-PEK/DDE (Tg∞) were found to be in relation with the initial molecular weight of the oligomer. The Tg∞ values for all samples closslinked were in the range of 183～215℃.

Key words: epoxy-terminated oligomer, phenolphthalein, polyaryletherketone, synthesis
