New Polyampholytes Based on Derivatized Polysaccharides:Synthesis,Aqueous Solution Properties and Applications

Synthetic polyampholytes combining both anionically and cationically charged species have been the focus of a number of studies due to their many potential applications^[1].However, there are few works that studied the polyampholytes derived from modified natural polymers. Recent work in our group has dealt with the grafting of a cationic monomer or a cationic monomer coupled with a neutral or anionic monomer onto carboxymethyl cellulose (CMC) as well as the grafting of a zwitterionic monomer onto hydroxyethyl cellulose (HEC) by using various initiation systems^[2-7]. Depending on the nature of used monomers, these modified polysaccharides can carry functional acidic and basic groups of different strengths.
