Abstract This Study deals with the Emulsion Polymerization of styrene monomer and the emulsion copolymerization of styrene and sodium styrene sulphonate using potassium persulphate and sodium bisulphate as redox pair initiation system and dodecylbenzene sodium sulphonate as an emulsifier. The results revealed that , the viscosity average molecular weights increased with Increasing the emulsifier and monomer concentrations , and decreased with Increasing the initiator concentration or temperature. |
