Physicochemical properties of N,N-allyl-N′-acylhydrazine copolymers with acrylonitrile

The physicochemical properties of high-molecular weight compounds based on N,N-diallyl-N′-acyllhydrazines were studied. Based on the results of thermal analysis it was established that sorbents are stable up to 160–210 °C; the destruction of the initial N,N-diallyl-N′-acyllhydrazines starts at lower temperatures. The stability of sorbents in various media, the values of static exchange capacities for hydrogen ions and hydroxide ions (\(\text{SEC}_{\rm{H}^{+}}\) and \(\text{SEC}_{\text{OH}^{-}}\)), and isoelectric points of the surface were determined. Samples for further study of the rare earth metals sorption were selected.
