The graft copolymerization of chloroprene rubber with methyl methacrylate in toluene solution has been carried out varying the concentration of monomer, initiator, CR, reaction time, and reaction temperature, etc.. It is observed that the grafring reaction follows conventional kinetic behavior under the present experimental conditions. Identification of grafting on to chloroprene rubber was obtained through characterization of the graft copolymer by infrared spectrometer.
