AbstractIrradiation of wool by short‐wavelength ultraviolet light in the presence of acrylate or methacrylate esters in dimethyl sulfoxide causes intermediate grafts (2–10) of polymer on the surface of the wool. The amount of grafting and homopolymerization and the evenness and regularity of photografted polymer are dependent upon the monomer used. With methyl acrylate, the reaction time, monomer concentration, and introduction of water as cosolvent affect the degree of fiber grafting and the amount and molecular weight of accompanying homopolymer. Polymers grafted onto wool by this technique change the tensile properties and the water desorption characteristics of the w
