摘要

首先用马来酸酐、对氨基苯酚为原料合成N-对羟基苯基马来酰亚胺(HPM)

然后用合成的HPM、4

4-二氨基二苯醚(ODA)和多聚甲醛为原料进行曼尼希反应合成出含双马来酰亚胺的苯并噁嗪(HPM-BOZ)

经高温固化后形成热固性树脂。用FTIR、1H NMR、13C NMR分析了HPM和HPM-BOZ的化学结构

证实了所得的为目标产物;用DSC对HPM-BOZ的固化特性进行研究

用TGA分析了HPM-BOZ的固化物的热稳定性;用SEM分析了树脂的断裂面。结果表明:HPM-BOZ在235℃和266℃出现了两个固化峰;在氮气条件下

热分解温度为410℃

失重5%的温度为438℃

在800℃的残碳率为60.2%。

Abstract

A novel bismaleimide-benzoxazine resin(abbreviated as HPM-BOZ)was synthesized by three steps. Firstly

N-p-hydroxylphenylmaleimide(HPM)was prepared from maleic anhydride and p-aminophenol. Secondly

HPM

4-2 amino diphenyl ether (ODA) and paraformaldehyde were used as raw materials to prepare HPM-BOZ with Mannich reaction. Thirdly

a novel bismaleimide-benzoxazine resin was fabricated by a specific curing process. The chemical structure of HPM and HPM-BOZ was characterized by FTIR

1H NMR and 13C NMR. Section fracture surface of the resin was analyzed by SEM. The curing behavior of HPM-BOZ was characterized by DSC with two peaks at about 235℃ and 266℃ appeared during its curing

respectively. TGA curves demonstrated that HPM-BOZ had excellent thermal stabilities under the condition of nitrogen

which began to decompose at 410℃ with 5% mass loss temperature of 438℃ and obtained 60.2% char yield at 800℃.
