摘要

以3-溴丙炔、腰果酚为原料，利用相转移催化反应合成了炔基化腰果酚树脂，并用FT-IR、1H NMR对炔基化腰果酚的化学结构进行了表征，结果表明在相转移催化剂存在条件下，3-溴丙炔和腰果酚通过Williamson成醚反应成功制备了目标产物。用TG研究固化后的炔基化腰果酚树脂热稳定性能，结果表明，固化后树脂的起始降解温度为419℃，800℃时的残炭率为14%，说明其具有很好的耐热性能。根据DSC曲线，用Kissinger和Flynn-Wall-Ozawa分别计算了热固化反应活化能，分别为143.46 kJ·mol-1和145.15 kJ·mol-1，热固化反应级数都接近1，因此说明这两种模式很适合这种体系。

Abstract

Propargyl cardanol was synthesized using cardanol and propargyl bromide by phase transfer catalyst reaction. The chemical structure of propargyl cardanol was characterized by FT-IR

1H NMR. The results indicated that propargyl cardanol as target compound was obtained through the Williamson ether reaction. Thermal stabilization of poly-propargyl cardanol was evaluated with TG. The initial weight-loss temperature of cured propargyl cardanol was 419℃ and char yield at 800℃ was 14%

which illustrated that the cured propargyl cardano owned well-deserved thermal stability. According to DSC curves

curing kinetic parameters were calculated by two thermo-analysis methods of Kissinger and Flynn-Wall-Ozawa. The respective apparent activation energies were 143.46 and 145.15 kJ·mol-1 respectively and the order of curing reaction both approached to 1

which illustrated that these two kinds of mode were suitable for this system.
