Abstract: Process for emulsification of chlorinated rubber and synthesis of graft copolymer of chlorinated rubber and methacrylic acid has been described. Effect of monomer concentration (chlorinated rubber: methacrylic acid) used for grafting on emulsion stability has been discussed. Graft copolymer fraction is separated from homopolymer polymethacrylic acid by soxhlet extraction in methanol and percentage of grafting and percentage grafting efficiency have been calculated from dry weight and acid value data of the sample before and after extraction; Effect of initiator concentration on percentage of grafting and percentage grafting efficiency has been studied and explained in the light of the mechanism of grafting. Graft copolymer has been characterized by Gel Permeation Chromatography and IR spectra. The paint based on chlorinated rubber emulsion is evaluated as a protective coating with special reference to its acid, alkali, water and humidity resistance.
