Studies on graft copolymerization of chitosan with synthetic monomers.

open access: yes, 2003
Graft copolymerization of acrylonitrile and methylmethacrylate onto chitosan using potassium persulfate as an initiator was studied. Evidence for graft-copolymerization was obtained by infrared spectroscopy and CP-MAS 13C-NMR data.
