SYNTHESIS AND RESEARCH OF POLYMER HYDROGELS ON THE BASIS OF HYDROLYSED POLYACRYLONITRILE AND EPICHLORHYDRIN

The article studies the synthesis of a highly swelling polymer hydrogel based on the interaction of epichlorohydrin with HYPAN. There was analyzed the influence of temperature and the concentration of initial reagents on gelforming in the reaction mixture and swelling degree of the extracted hydrogel, also were established optimal conditions for hydrogel synthesis. The swelling kinetics of a hydrogel-based on HYPAN (hydrolyzed polyacrylonitrile) and epichlorohydrin were learned, and there was shown the optimum degree of grinding during the process of the hydrogel swelling in water. The article explains information on the synthesis of new macromolecular hydrogel based on HYPAN(hydrolyzed polyacrylonitrile) and CMTH (Carboxymethylcellulose) with new sewing agents, looked through synthesized products and determined their structure by various Physico-chemical and physic mechanical methods, shows the making and developing of industrial production of import-substituting products from local raw materials and industrial wastes to saturate the domestic market. The resulted hydrogel is used where there is not enough water, in places where the earth is rich in salts, to save mineral fertilizer and other spheres for the complete or partial solution of the problems.
