采用DSC,DMA,FTIR和SEM等方法研究了PC/E51/TEPA和PC/E51/DDS两种共混体系的固化、结构特征、力学和热性能实验表明:体系的固化反应可按原位固化方式进行,PC对固化反应起促进作用共混体系具有均相结构特征,两组份间存在有较强的氢键作用,从而提高了体系的Tg、模量、密度和热稳定性PC/E51/TEPA样品透明,两个体系对冲击韧性均略有改善
The investigations on difunctional epoxy(DEGBA)/4, 4-diaminodiphenylsulfone(DDS)system(I)and DEGBA/tetraethylenepentamine(TEPA)system (Ⅱ), both of which were modified withpolycarbonate(PC)by melting process are reported. Dynamic mechanical spectroscopy (D
