Radiation synthesis, characterization and amidoximation of N-vinyl-2-pyrrolidone/acrylonitrile interpenetrating polymer networks
Interpenetrating polymer networks (IPNs) were synthesized by irradiating acrylonitrile solutions of poly(pyrrolidone) with Co-60-gamma rays. The conversion to insoluble IPN structure was characterized using FT-IR and thermal analysis ies of IPN was carried out in aqueous solutions of NH2OH . HCl-NaOH at 50 degrees C. The conversion of amidoximation was followed by using FT-IR spectrophotometer and conversion of nitrile groups to amidoxime was determined as percentage. The structure of amidoximated IPN was characterized by FT-IR and thermal methods as well.
