Abstract
2-acrylamide-2-methyl propane sulfonic acid (AMPS) was grafted onto guar macromolecules using biodegradable guar as raw material, persulfate potassium (K2S2O8) and sodium sulfite(Na2SO3) redox system as initiators. The different influence factors on graft reaction were investigated to determine the ideal reaction conditions. The sulfonated guar with high viscosity has good salt resistance, compatibility and stability with the toothpaste components, which can improve toothpaste tailing phenomenon and meet the requirements of water-based adhesive and thickening agent in other industries.
