실험 절차

32.21 Gram of 3,3',4,4'-benzophenonetetracarboxylic dianhydride in 69.1 g of N-methyl-2-pyrrolidone was heated to 80° C., and 9.21 g of ethanol was added and reacted at 100° C. for 2 hr to form a solution of benzophenone-tetracarboxylic ester. To this solution was added 20.01 g of 4,4'-diaminodiphenyl ether and reacted at 80° C. for 3 hr. The thus obtained solution of poly(amic acid) ester oligomer was found to have a viscosity of 2 poises at 25° C.
