A new diamine 5,5 '-bis[4-(4-aminophenoxy)phenyl]-hexahydro-4,7-methanoindan (3) was prepared through the nucleophilic displacement of 5,5'-bis(4-hydroxylphenyl)-hexahydro-4,7-methanoindan (1) with p-halonitrobenzene in the presence of K 2 CO 3 in N,N-dimethylformamide (DMF), followed by catalytic r
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
