Abstract
Interpenetrating polymer networks (IPNs) were synthesized by irradiating acrylonitrile solutions of poly(N-vinyl-2-pyrrolidone) with 60Co-γ rays. The conversion to insoluble IPN structure was characterized using FT-IR and thermal analysis methods. The amidoximation of polyacrylonitrile moieties of IPN was carried out in aqueous solutions of NH2OH·HCl–NaOH at 50°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.
