Methyl methacrylate (MMA) can be polymerized by the charge-transfer complex formed by the interaction of melamine (MM), MMA and carbon tetrachloride in a non-aqueous solvent like dimethyl sulphoxide (DMSO) or N-N-dimethylformamide. The polymerization can be accelerated by Lewis acids like Fe 3+. Thi

Polymerization of methyl methacrylate (MMA) by the charge-transfer complex formed by the interaction of 2,2-bipyridine (bpy), MMA, and carbon tetrachloride (CCl 4 ) was studied in dimethylsulfoxide (DMSO) at 60ะC. The rate of polymerization (R p ) is sensitive to the [CCl 4 ] at low concentration of
The triphenylphosphine (TPP) initiated polymerization of methyl methacrylate (MMA) in dimethyl sulphoxide (DMSO) has been studied. The polymerization was found to be solvent-sensitive and could be accelerated by Lewis acids like Fe 3รท . Kinetic studies showed that the propagation was free radical in
