Receiving polycomplexons with functional groups of poliamfolitny character on the basis of the polyacrylonitrile fiber modified by hexamethylenediamine "Nitron" is considered. Existence as a part of a polycomplexon the amine and carboxyl groups is proved by the IK methods of spectroscopy and electrometric titration. Kinetic regularities of receiving polycomplexons and their sorption ability in relation to copper ions are studied. Change thermodynamic functions in the course of binding of ions of copper from ammoniac solutions is determined by a polycomplexon and its high sorption ability to this ion is shown.

Keywords: IR spectroscopy, polycomplexons, sorption capacity.

Interaction of products of thermal destruction of fluoroelastomer by SKF-26 with calcium hydroxide is studied. Kinetic parameters of process in isothermal conditions and temperature and time characteristics of full binding of halogen in ecologically safe products are determined.

Keywords: fluoroelastomer, halogens, fluoropolymers.
