     zinc stearate was synthesized by precipitation method through two steps; neutralization of stearic acid by sodium hydroxide then double decomposition using zinc sulphate to precipitate zinc stearate. mass balances of the two steps were calculated and the physical properties of the prepared zinc stearate were measured and compared to standard. it was characterized and incorporated it into natural rubber in the absence and presence of some filler through mixing process of rubber. the vulcanization process was carried out at 142 °c. the rheological properties of natural rubber mixes were measured using oscillating disc rheometer. the plysico-mechanical properties of the vulcanizates were determined using tensile testing machine. it was found that, partial and complete replacement of synthesized zinc stearate instead of the conventional zinc oxide and stearic acid; enhanced the physico-mechanical properties of natural rubber.
