摘要
采用K2 S2 O8/NaHSO3 引发甲基丙烯酸甲酯 (MMA)在羟丙基甲基纤维素 (HPMC)上接枝聚合 ,考察了反应条件 ,如引发剂浓度、温度。
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.
