Tailor-made chitosans for drug delivery

Graft copolymers of chitosan were prepared using acrylic and methacrylic acids. The grafting was initiated by eerie ion. Experimental parameters such as the concentrations of monomer and the initiator on grafting were investigated. The percent grafting, grafting efficiency and percent conversion of the monomer were also analysed. The graft copolymers were further characterized by infrared spectroscopy and gravimetric analysis. These graft...
