Aromatic polyetherimides were synthesized from a fluorine containing aromatic carboxylic acid dianhydride, 2,2-bis [4-(3,4-dicarboxyphenoxy)phenyl]hexafluoropropane dianhydride (6F-BABPA) and five typical aromatic diamines including 1,1-bis(4-aminophenyl)-1-phenyl-2,2,2-trifluoroethane (3F-DAM) by t
New aromatic tetracarboxylic dianhydride, having isopropylidene and bromo-substituted arylene ether structure 3,3Ј,5,5Ј-tetrabromo-2,2-bis[4-(3,4-dicarboxyphenoxy)phenyl]propane dianhydride, was synthesized by the reaction of 4-nitrophthalonitrile with 3,3Ј,5,5Ј-tetrabromobisphenol A, followed by al
## Abstract A soluble polyimide was synthesized from 2,2′‐bis[4‐(3,4‐dicarboxyphenoxy)phenyl]propane dianhydride (BPADA) and 3,3′‐dimethyl‐4,4′‐diaminodiphenylmethane (DMMDA) by a two‐step method, and it had good solubility both in strong bipolar solvents and in common low‐boiling‐point solvents. T
