摘　　要：合成了含柔性链（Ｃ１０）的液晶双马来酰亚胺与双烯丙基氧基联苯的共聚物，经ＦＴＩＲ、ＤＳＣ、偏光显微镜表征了该共聚物的结构及液晶性，结果表明：二者发生共聚反应，且共聚反应快于均聚反应，形成的共聚物具有较好的热致液晶性。Copolymers based on liquid crystalline bismaleimide containing flexibile chains and 4,4 diallyloxylbiphene were synthesized.Copolymers were characterized by FTIR,DSC,polarized light microscopy and scaning electron microscopy.Good nematic liquid crystalline characters were observed in the monomers,copolymers and crosslinked networks.
