Summary In order to ascertain the role of mercaptan groups during grafting, the graft copolymerization of methyl methacrylate (MMA) onto reduced Indian Chokla Wool fibers in an aqueous medium was investigated using potassium peroxydiphosphate (PP) as initiator. The percentage of grafting was determined as a function of concentration of initiator PP, monomer MMA and sulfuric acid, time, temperature and the presence of solvents. The molecular weight of the grafted polymer decreased as the extent of grafting increased. A kinetic scheme was developed based upon the dependence of the rate of grafting upon the reactant concentrations.
