【摘要】 采用甲苯二异氰酸酯与自制的对苯二甲酸二缩水甘油酯生成聚口恶唑烷酮。并用红外光谱、DSC、热重分析仪对其进行表征。检测出其玻璃化温度为110℃,其失重5%时需要的温度为257℃,并研究了其绝缘性能。更多还原

【Abstract】 A new kind of polyoxazolidone was prepared by tolylene diisocyanate and diglycidyl p-phthalate.The polymer was characterized by IR,DSC and TG.The result shows that the glass temperature of this polymer was 110℃,and weight loss temperature was 257℃.The electric insulation of the polymer also was studied.更多还原
