| Abstract: | The graft copolymerization of methyl methacrylate onto Hydoxyl-propyl-Methyl cellulose has been carried out using K 2S 2O 8/NaHSO 3 redox system. The graft conditions such as initiator concentration, reaction temperatures, reactiontime ,monomer concentrations have been thoroughly studied .The graft yield(G%) and efficiency(E%) increases with increase in initiator concentration up to 1.0mmol/L and then decreases, it also increases with increase in reaction time ,monomer concentration and decreases in temperature. The graft copolymerization was confirmed by IR. |
