1.. A process comprising polymerizing a polymerizable monomeric compound containing a polymerizably reactive CH =C group in an aqueous medium at a pH not greater than 3.5 in the presence of a ceric salt which It will be noted in the above examples, and particularly with regard to Examples 27-33 relative to the graft polymerization of suitable monomers on the cellulosic backbones of materials such as cotton fabric, regenerated cellulose fabric, viscose rayon fabric, paper, paper pulp, wood, wood pulp, and the like, that certain advantages of the present process, namely its ability to operate at low temperatures, and more specifically room temperature, and the fact that excessive loss of monomer due 'to homo polymerization in the bath are obviated. This is particularly evident with regard to Example 33, wherein the graft polymer was insoluble in both cupridiethylene diamine and dimethyl foramide, indicating that the cellulose molecule was modified and that no free polyacrylonitrile was present. This is believed to indicate clearly that the polyacrylonitrile is grafted onto the cellulosic backbones of the material. I
