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

## Abstract A series of novel bis(phenoxy)phthalideโ€containing poly(amideโ€imide)s 3 were synthesized via direct polycondensation of 3,3โ€bis[4โ€(4โ€aminophenoxy)phenyl]phthalide (BAPP) with various aromatic bis(trimellitimide)s 2 in __N__โ€methylโ€2โ€pyrrolidone (NMP) using triphenyl phosphite and pyridi
