Abstract: The present invention relates to new compounds which are graft copolymers of cellulose and polyacrylthiomide with the general formula

WHEREIN A is cellulose m is the degree of polymerization of cellulose ranging from 150 to 2,000 N IS THE DEGREE OF POLYMERIZATION OF POLYACRYLTHIOAMIDE RANGING FROM 400 TO 4,000; METHOD OF PRODUCING THESE NEW COMPOUNDS AND TO APPLICATION THEREOF. The method of producing said compounds resides in treating graft polymers of cellulose and polyacrylonitrile with hydrogen sulphide or with salts of hydrosulphuric acid in an aqueous or an organic medium at a temperature of 60*-100* C and subsequently isolating the target product. The herein-proposed compounds can find application as electronexchange complex-forming materials in chemical industry, metallurgy and in other industries.
