2,2-Azobis(2-methylpropionitrile) (AMPN) was investigated as initiator for the graft copolymerization of methacrylic acid (MAA) onto chitosan. A number of variables in the grafting reaction were investigated, including AMPN and monomer concentration, material to liquor ratio, duration, and temperature of polymerization reaction. The graft copolymers were evaluated in terms of graft yield, homopolymer,...
Ionic exchange resin was prepared via grafting of β-cyclodextrin itaconate (CDI) onto chitosan. CDI was prepared by esterification of β-cyclodextrin with itaconic acid using a semidry process. The esterification reaction of β-CD was carried out using [IA]; 2 mol/mol of CD, M/L ratio; 1:0.6, temperature 100 °C, [catalyst]; 0.5 mol/2 mol IA and in the absence of catalyst. The double bonds of CDI were...
