CYCLOPOLYMERIZATION OF DIVINYL MONOMER WITH MANGANESE(VII)-THIOL REDOX PAIR

Polymerization of non-conjugated divinyl monomer N,N'-methylene bisacr ylamide was studied with a novel redox pair of manganese (VII)-thiol i n a homogeneous gel-free state, under varying conditions of concentrat ion, temperature, pH and ionic strength, and the kinetic results were interpreted by a suitable mechanistic sequence from among various poss ibilities. Absence of gelation is attributed to the formation of a cyc lic polymer. An attempt is made to correlate the structure of the redu ctant-oxidant complex with the observed kinetic results.
