Application

m-Toluidine may be used to form pyrrole/m-toluidine copolymers via oxidative polymerization.

General description

m-Toluidine (MT) is an aniline derivative that behaves as a fragile glass forming liquid. Its dielectric relaxation process, glass transition relaxation, relaxation modes and slow secondary relaxation have been studied. The analysis of MT crystalline phase by powder X-ray diffraction shows that it belongs to monoclinic space group, P21/c. Its structure is held together by N-H...N hydrogen bonds and van der Waals interactions.
