摘要
本文以联苯二酚为原料,制备了双烯丙基联苯醚与双马来酰亚胺的共聚物。经DSC、WAXD和热台偏光显微镜表征,该共聚物具有较强的热固化性能和液晶特征。经等温固化研究表明,交联密度越大液晶聚合物网络的清亮点越低,而且将近晶型液晶态保留在网络中。这为制备新型的改性双马来酰亚胺另辟新径。
Diallybiphenyl ether/bismaleimide copolymer was prepared with diphenol as raw material and the thermo-setting and liquid crystalline characteristics of the copolymer were investigated with DSC, WAXD and hot stage polarized microscopy. The relation between the liquid crystalline texture and the crosslink density was also studied with isothermal curing method. These studied have opened a new way to prepare noval modified bismaleimide.
