摘要： A co-polyimide based upon a mixture of 4,4'-oxydiphthalic dianhydride (ODPA) and 3,4,3',4'-biphenyltetracarboxylic dianhydride (BPDA) as the dianhydride component and either 4,4'-oxydianiline (ODA) or paraphenylene diamine as the amine component is disclosed. The molar ratio between the ODPA and BPDA ranges from 3:1 to 1:3. The co-polyimide may either be formed as a random copolymer, or as a block copolymer where the blocks are based upon blocks of polymer containing ODPA and blocks of polymer containing BPDA provided that the molar ratios of ODPA and BPDA are in the ratio of 3:1 to 1:3.
