Abstract

RECENTLY, Evans and co-workers1,2 have examined the polymerization of methyl methacrylate in aqueous solution, when the initiation of polymerization was by hydrogen peroxide in the presence of ferrous ions. The suggested reaction scheme was as follows : Algebraic expressions were derived giving the rate of disappearance of monomer and also the distribution of molecular weights in terms of concentrations and the rate constants of individual reaction steps.
