New triarylamine‐based polymers have been synthesized by polyaddition of 4‐tolyldiphenylamine (TDPA) with 1,4‐divinylbenzene (DVB) or 1,3‐diisopropenylbenzene (IPB) in the presence of p ‐toluenesulfonic acid. 1 H NMR spectra revealed that DVB units were linked to TDPA units not only at p ‐position but also at m ‐position to aryl group in TDPA‐DVB polymer. On the other hand, IPB was less reactive and TDPA‐IPB polymer was achieved only in a p ‐linkage. The incorporation of DVB or IPB did not significantly affect the electronic structure of TDPA unit as confirmed by UV spectra and cyclic voltammetry. From differential scanning calorimetric (DSC) measurements, glass transition temperatures of TDPA‐DVB and TDPA‐IPB polymers were estimated to be 169°C and 132°C, respectively. The resulting polymers have good solubility in conventional organic solvents (e. g. chloroform, tetrahydrofuran and toluene).
