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 acrylamide and N, N-dimethyl acrylamide were grafted on the cellulose acetate backbone using y-radiation from 60 Co source. Different parameters like total dose, concentration, temperature and time were varied during grafting of N, N-dimethyl acrylamide. Extent of grafting followed the order AM> Me AM > N, N-dimethyl A M and for N, N-dimethyl acrylamide highest grafting was obtained at 40% monomer concentration, at 60°C with 1.37 M rad dose. Probable reasons for difference in grafting percentage for different monomers are discussed.
