Polymerization of non‐conjugated divinyl monomer N , N ′‐methylene bisacrylamide was studied with a novel redox pair of manganese (VII)–thiol in a homogeneous gel‐free state, under varying conditions of concentration, temperature, pH and ionic strength, and the kinetic results were interpreted by a suitable mechanistic sequence from among various possibilities. Absence of gelation is attributed to the formation of a cyclic polymer. An attempt is made to correlate the structure of the reductant–oxidant complex with the observed kinetic results.
