Graft copolymerization methacrylamide onto pectin in homogeneous solution

Abstract

In the present paper, attention is paid to chemically modified polysaccharide, pectin, by graft copolymerization of methacrylamide (MAAm) in an aqueous medium using ammonium persulfate as an initiator under argon atmosphere and determination of grafting parameters produced copolymer. The structure of pure pectin and grafted with monomer was characterized by FTIR, SEM spectroscopies and TGA analysis. The thermal properties of pure pectin and grafted with monomer were evaluated with a simultaneous thermal analysis system. The results showed that the thermal stability of grafted polymethacrylamide samples was remarkably improved.
