Wood pulp was copolymerized with acrylonitrile as a monomer using the xanthate grafting method. This method takes advantage of the capability of cellulose xanthates t o form a redox couple with a suitable oxidation agent.

The redox system cellulose xanthogenatehydrogen peroxide was compared with the ionic xanthate method of grafting of cellulose. It was revealed that the manner of the addition of hydrogen peroxide to the cellulose xanthate plays a role. The graft yields and the reactivities of the monomers depend on
