Methyl methacrylate (MMA) and ethylacrylate (EA) have been graft copolymerized onto Himachali wool in aqueous medium by using a ferrous ammonium sulfate-hydrogen peroxide (FAS-H/sub 2/O/sub 2/) system as redox initiator. Percentage of grafting has been determined as functions of concentration of monomer, molar ratio of (FAS)/(H/sub 2/O/sub 2/), time, and temperature. Percentage of grafting is found to depend upon the molar ratio of (FAS)/(H/sub 2/O/sub 2/). An attempt has been made to compare the reactivities of the acceptor monomer (MMA and EA) with that of the donor monomer (VAc) toward grafting onto wool.
