A series of copolyimides (co-PIs) with high molecular weights, excellent mechanical properties, heat-resistant properties, and good solubilities in organic solvents were synthesized from six kinds of commercial dianhydrides (IIa-f) and 1,4-bis(4aminophenoxy)-2-tert-butylbenzene (I). Monomers (IIa-d)
Preparation and characterization of organosoluble copolyimides based on a pair of commercial aromatic dianhydride and one aromatic diamine, 1,2-bis(4-aminophenoxy)-4-tert-butylbenzene, series

A bis(ether amine) containing the ortho-substituted phenylene unit and pendant tert-butyl group, 1,2-bis(4-aminophenoxy)-4-tert-butylbenzene, was synthesized and used as a monomer to prepare polyimides with six commercial dianhydrides via a conventional two-stage procedure. The intermediate poly(ami
## Abstract A new kind of pyridineβcontaining aromatic diamine monomer, 4βphenylβ2,6βbis[4β(4βaminophenoxy)phenyl]βpyridine (PAPP), was successfully synthesized by a modified chichibabin reaction of benzaldehyde and a substituted acetophenone, 4β(4βnitrophenoxy)βacetophenone (NPAP), followed by a r
