In this paper, prepolymer method of adding styrene to the adduct polymer which was prepared by additive reaction of maleic anhydride to liquid hydroxylterminated polybutadiene (HT-PB) and one shot method of mixing HT-PB, maleic anhydride and styrene at the same time, were tested. The effect of quantity of maleic anhydride and styrene on mechanical property of the compound that was cured by these methods was investigated.It became apparent that the mechanical property of cured polymer which was obtained by prepolymer method was superior to that of one shot method, and in case of the former, compounds indicating broad elasticity from elastic to plastic with an increasing quantity of maleic anhydride and styrene were obtained.
