“…To the best of our knowledge, the first PI containing TPA was prepared by Vasilenko et al [18] in 1991, followed by Nishikata et al [19], who prepared PIs containing TPA derivatives with a methoxy substituent in the para position. The methoxy substituent in the para position is important because TPA derivatives could be dimerised during the anodic oxidation pathway [20], which can be prevented by incorporating electron donating groups at the para position, which also creates stable cationic radicals with lower potential [21].…”

“…It should be noted that no solubility data has been reported for poly (triphenylaminepyromellitimide ) . 4 So, PM-TPM seems to be one of the very few poly-( pyromellitimides ) that are soluble in organic solvents.…”

“…In order to overcome this problem, the derivatives of 4,4' diaminodiphenylmethane, such as 4,4'-diaminotetraphenylmethane * or 1,l-bis (4-aminophenyl) -1-(4-ethynylphenyl) -2,2,2-trifluoroethane,2 as well as 4,4'-diaminotriphenylamine, [3][4][5] have been used as monomers in several previous studies for the synthesis of aromatic polyamides and polyimides.…”

SYNOPSISAromatic polyamides and polyimides were synthesized from 4,4'-diaminotriphenylmethane (DA-TPM) for studying their solubility, thermal, and mechanical properties. The polymers were found to be soluble in amide solvents and pyridine, and this could be attributed to the practically free rotation of the polymer chain segments around the bridging group within the DA-TPM and the effect of its pendant phenyl ring. The polyimides and polyamides exhibited well-distinguished glass transition in the range of temperatures, which is typical for flexible-chain polymers. For the polyimides, significant differences in solubility and mechanical properties were observed between the samples prepared by chemical and thermal imidization of poly(amic acids). Thermal imidization brought about remarkably less soluble brittle films. 0 1995 John Wiley & Sons, Inc.

“…[23] Earlier research carried out for the structurally similar N,N-diamine triphenylamine (DA-TPA) showed that the incorporation of a pendant phenyl group into the polymer backbone is a successful approach to increase solubility and processability of PIs. [15,20,[25][26] The synthesis of DA-TPM developed in our group is simple and highly efficient using commercially available and cheap starting materials such as aniline and benzaldehyde. This is a big advantage in comparison to N,N-diamine triphenylamine, whose synthesis is much more complicated and required expensive reagents.…”
