摘要

以酚酞、烯丙胺、多聚甲醛为原料

合成了具有烯丙基的新型酚酞型苯并嗪树脂(PT-ala)。用FT-IR、1H NMR和DSC表征了其结构和固化特性

并用TG-DTG方法对其聚合物在氮气中的热分解过程动力学进行了详细的研究。结果表明:用Kissinger法和Ozawa法求得的聚合物热分解活化能分别为189.65 kJ·mol-1和215.11 kJ·mol-1;用Coats-Redfern法证实了酚酞烯丙胺型聚苯并嗪的热分解反应为一级反应;在氮气氛中维持60 s寿命的最高使用温度为285℃。

Abstract

Novel allyl-containing phenolphthalein benzoxazine(PT-ala resin)was synthesized from phenolphthalein

allylamine and paraformaldehyde.The chemical structure of PT-ala resin was characterized by FT-IR

1H NMR

and the curing behavior of PT-ala resin was studied by DSC.TG and DTG were used to study the thermal degradation kinetics of PT-ala resin in N2.The kinetic parameters were calculated by the methods of Kissinger and Ozawa

and the apparent degradation reaction order of PPT-ala was 1 in N2

thermal degradation activation energies were 189.65 kJ·mol-1 and 215.11 kJ·mol-1 respectively.The temperature of 60 s lifetime was 285℃ in N2.
