| Abstract: | The graft copolymerization of methyl methacrylate onto agarose using ceric ammonium nitrate as initiator was carried out. The effects of initiator and monomer concentration,temperature, reaction time and feed procedure on the conversion of monomer, percentage grafting, grafting efficiency and rates of polymerization were investigated. The infrared spectra and differential thermal analysis indicated the products were graft copolymers. The glass transition temperature(Tg) of the copolymers decreased with the increase of percentage grafting. The copolymers can be well hot-pressed and dissolve in some organic solvents. |
