Manganese (Iv)-Initiated Grafting of Trimethylallylammonium Chloride Onto Carboxymethylcellulose

Graft copolymerization of cationic monomer trimethylallylammonium chloride onto anionic carboxymethylcellulose has been investigated in aqueous medium using potassium permanganate/sulphuric acid redox system as initiator, involving the identification of grafting, the mechanism for grafting and various factors affecting grafting. The prepared cellulosic copolymers with amphoteric functional groups have been found to be effective to retard the hydration of clay minerals, showing a potential use as new clay-hydration suppressant for oilfields.
