The grafting product of maleic anhydride onto cyclizednatural rubber have been produced in the presence of trimethylol propane triacrylatecomonomer which is processed in an internal mixer 150°C 80 rpm. In this research, the ratio of Tris / maleic anhydride used is 1: 2; 1: 1 and 2: 1.All grafted product was purified to determine the degree of grafting for each graft product by the titration method. The degree of grafting increases with increasing trimethylol propane triacrylate mole ratio. The highest degree of grafting is obtained in moles ratio of 2: 1 which is to 5.88%.
