Abstract: New polyurethane membrane from hydroxylated rubber seed oil has been prepared in this study.Hydroxylated process of rubber seed oil improved 135.30% of hydroxyl number and decreased 73.91% of iodine number of rubber seed oil.Optimum polyurethane membrane was obtained at the composition of hydroxylated rubber seed oil:hexamethylene-1,6-diisocyanate was 5:7 v/w.The membrane was homogeneous, dry, smooth, slightly stiff and brownish yellow.The clean water flux and rejection factor of the membrane were 0,544L / m 2 .h.bar and 98.86%, respectively.FTIR spectra indicated the formation of urethane bond (N-H at 3308 cm -1 ).Thermal analysis showed two stages of decomposition at 223 o C and 386°C.The membrane exhibited a strong and elastic properties with a tensile strength of 1.13 kgf/mm 2 and elongation 215.36%.
