Radiation grafting of N,N'-dimethylacrylamide and 2-hydroxyethylmethacrylate onto polypropylene films by one step method

Abstract:

The work presented herein reports on polypropylene films grafted with N,N'-dimethylacrylamide and 2-hydroxyethylmethacrylate. The grafted films were obtained by an oxidative pre-irradiation method in one step using a gamma source of 60Co. The optimal conditions such as reaction time, monomer concentrations and radiation doses were investigated. Characterization of the grafted polymers was carried out through FTIR-ATR, TGA, DSC, and swelling. Grafts onto polymeric films between 10 and 850% were obtained at doses from 20 to 150kGy and a dose rate of 8.3kGy/h. © 2012 Elsevier Ltd.
