## Abstract Having previously demonstrated that the polyimide derived from 3,3′,4,4′‐biphenyltetracarboxylic dianhydride (BPDA) and 1,2‐bis(4‐aminophenoxy)benzene [termed triphenyl ether catechol diamine (TPEC)] exhibited superior tensile properties in addition to good thermal properties, we now pr
Four kinds of 3,3 ,4,4-benzophenone tetracarboxylic dianhydride (BTDA) -pyromelliitic dianhydride (PMDA) alternating polyimide (BTDA-PMDA API) were obtained by reacting 1 mol BTDA with 2 mol diamines to form BTDA chainextended diamines (BTDA CED), followed by the addition of 1 mol PMDA to yield the
