STRUCTURAL INFLUENCE ON GRAFTING OF ACRYLAMIDE BASED MONOMERS ON CELLULOSE-ACETATE

Radiation initiated grafting is a very promising area in the field of polymers. To make a backbone hydrohilic different vinyl monomers have been grafted onto the polymeric backbone. Here acrylamide, methyl acry lamide and N, N-dimethyl acrylamide were grafted on the cellulose acet ate backbone using gamma-radiation from Co-60 source. Different parame ters like total dose, concentration, temperature and time were varied during grafting of N, N-dimethyl acrylamide. Extent of grafting follow ed the order AM > Me AM > N, N-dimethyl A M and for N, N-dimethyl acry lamide highest grafting was obtained at 40% monomer concentration, at 60 degrees C with 1.37 M rad dose. Probable reasons for difference in grafting percentage for different monomers are discussed.
