Abstract: | Grafting of N,N-dimethyl-N-methacryloxyethyl-N-(3-sulfopropyl) ammonium (DMMSA) onto chitosan using ceric ammonium nitrate as an initiator was studied under nitrogen atmosphere in 2% wt. acetic acid solution. The grafted polymer was confirmed by FT-IR spectroscopy. The extent of grafting could be adjusted by controlling the appropriate reaction conditions. The maximum percentage of grafting about 50% was obtained under optimum condition. A representative grafted copolymer was characterized by thermogravimetric analysis and chitosan was used as reference. |
