Notes:
The polymerization of N-vinylcarbazole (NVC) initiated by SOCl2 in benzene and nitrobenzene solvents was studied at 32°C. Rp is first order with respect to SOCl2 concentration and also to NVC concentration up to a certain NVC concentration, after which it falls. Rate and the molecular weight increase with increasing dielectric constant of the medium. The rate and molecular weight are depressed by the addition of amines, thiophene, and water. The degree of polymerization is independent of SOCl2 and NVC concentration. A conventional cationic mechanism has been suggested, and a suitable kinetic scheme has been proposed in conformity with the findings.
