Doctoral Dissertations
"The emulsion polymerization of methyl methacrylate initiated by ultrasound has been studied at ambient temperature using sodium lauryl sulfate as the surfactant.
The source of the free radical for the initiation process was found to come from the degradation of the sodium lauryl sulfate presumably in aqueous phase. The weight average molecular weight (Mw) of the poly (methyl methacrylate) obtained varied from 2,500,000 to 3,500,000 g mole-1 and the conversion for the polymerization was up to 70%.
The polymerization rate, the number of polymer particles generated and the free radical concentration in initiation process were found to increase with …
