Pyrrole Oxidative Polymerization By Manganese Oxide (Iv) On Silica Gel Surface

The study of pyrrole oxidative polymerization in toluene localized on the surface of silica gel modified with manganese oxide (IV) was carried out. The kinetics of pyrrole oxidative polymerization on the surface was established, a kinetic model was proposed, and its parameters were calculated. It was shown that the activation energy is close to free energy of the viscous toluene flow that indicates diffusion control of the process. The changes of the specific surface area of silica gel and the pore volume distribution along the radii during the modification with manganese dioxide and the subsequent polymerization of pyrrole were determined.
