Preparation and curing method of benzocyclobutene-containing unsaturated ester imide monomer

The invention relates to a preparation and curing method of a benzocyclobutene-containing unsaturated ester imide monomer. The chemical structural general formula of the benzocyclobutene-containing unsaturated ester imide monomer is # imgabs0, wherein R1 is # imgabs1 # imgabs2 #, and R2 is H, alkyl and aromatic hydrocarbon. The monomer is dissolved in most organic solvents, has excellent processability and can be directly heated, melted, cured and molded or prepared into a polyimide film through a tape casting method, and a polyimide material obtained after curing has excellent thermal stability, high transparency and excellent dielectric property. 本发明涉及含苯并环丁烯的不饱和酯酰亚胺单体的制备及固化方法，其化学结构通式如下：#imgabs0#其中R1为：#imgabs1##imgabs2#R2为：H，烷基，芳香烃。该单体溶于大多数有机溶剂中，具有优良的加工性能，可直接加热熔融固化成型或通过流延法制备聚酰亚胺薄膜，固化后得到的聚酰亚胺材料具有优良的热稳定性，高透明度，优良的介电性能。
