To improve the compatibility of guar with other components and salt tolerance,2-acrylamide-2-methyl propane sulfonic acid(AMPS)is grafted onto macromolecular structure of guar gum by using biodegradable guar gum as raw material and potassium persulfate(K2S2O8)and sodium sulfite(Na2SO3)as redox initiation system.The influence of AMPS content,initiators content,initiators feeding time,reaction time,reaction temperature,liquor radio,ethanol percentage of dispersant on grafting efficiency is investigated to get...
