氨基二苯醚-双马来酰亚胺共聚树脂及其玻璃布层压板的研究

Study on Glass-Cloth Reinforced Laminates Based on ANDPOBMI Resin

本文介绍了一种新型耐热基体树脂 -氨基二苯醚树脂 (ANDPO)与双马来酰亚胺 (BMI)共聚物 ,研究了氨基二苯醚 -双马来酰亚胺 (ANDPOBMI)预聚物的制备工艺及溶解性能。以 ANDPOBMI预聚物制备了玻璃布层压板 ,考察其韧性、电性能及热老化性能。

ANDPOBMI resins were synthesized by copolymerizing aminobenzyl diphenyl ether oligomer (ANDPO) with bismaleimide (BMI) and the glass-cloth reinforced laminates based on the resin were prepared in this paper.The solubility of the resin prepolymers in different solvents were investigated,the electric resistivity,flexural strength at ambient and high temperatures,heat ageing were tested.The results show that the resin prepolymers are dissoluble in common low boiling-point solvents and the laminates have high electric resistivity and flexural strength at high temperatures.
