Triethylamine Oxide and lron(II) as Initiator of Methylmethacrylate Polymerization

Department of Physical Chemistry, Indian Association for the Cultivation of Science. Jadavpur, Calcutta-700 032. Manuscript received 14 September 1976, revised 15 April 1977, accepted 4 July 1977 Triethylamine-oxide-Fe2+ redox system has been found to be an efficien initator of aqueous polymerization of methylmethacrylate. Its mechanism has been found to be basically similar to the electro transfer mechanism of H2O2-Fe2+ or, N-halomine-Fe2+ as initiator. This system incorporates only the amino end group (no hydroxyl} into the polymer to an extent of about one group per polymer molecule. A large portion of the total amino groups introduced into the polymer are quanternary in nature. This Initiator system proves to be useful for the preparation or polymers containing amino groups at one end onl
