Aromatic soluble polyamides and copolyamides having hexafluoroisopropylidene and isopropylidene moieties in the molecular structure of polymer chain were prepared by reacting the aromatic diacid chlorides and fluorine or nonfluorine containing aromatic diamines using low-temperature polycondensation
A new cardo diamine monomer, 5,5-bis[4-(4-aminophenoxy)phenyl]-4,7methanohexahydroindane (II), was prepared in two steps with high yield. The monomer was reacted with six different aromatic tetracarboxylic dianhydrides in N,Ndimethylacetamide (DMAc) to obtain the corresponding cardo polyimides via t
