ABSTRACT:
A method for obtaining graft copolymers of cellulose or protein fiber with vinyl monomers, comprising the steps of impregnating cellulose or protein fiber with an aqueous solution of ferrous salt, removing excessive ions of ferrous iron, and grafting vinyl monomers to cellulose or protein fiber from an aqueous solution, aqueous emulsion or aqueous dispersion of a vinyl monomer, containing hydrogen peroxide and a reducing agent. The latter is hydrazine sulfate, sodium sulfide, glucose, sodium hypophosphite, sodium bitartrate or hydroquinone taken in an amount of 0.002 to 0.02 percent by mass. The method provides for a high rate of graft polymerization and rules out the formation of a free homopolymer in the reaction mixture. It can be carried out as a continuous and batch process.
