Title: Polymerization of Vinyl Monomers in the Presence of Surface Active Agents. II. The Rate of Polymerization of Methyl Methacrylate
Abstract: Abstract The polymerization of methyl methacrylate in the presence of sodium tetrapropylenebenzenesulfonate(ABS) in an aqueous system without any ordinary initiators was examined kinetically. The rate of polymerization of methyl methacrylate is dependent on the initial concentrations of methyl methacrylate and ABS, and expressed by the equation: Rp∝[ABS]0.37[MMA]0.32 The apparent activation energy of the polymerization is about 3 kcal/mol. It was confirmed by electron microscopic observation that the number of polymer molecules is in the same order as that of the micelle particles in the polymerization system.
