Hydrophobic terpolymers ethylene/vinyl alcohol/vinyl stearate, of three different compositions, have been obtained by reaction of a commercial ethylene/vinyl alcohol copolymer (EVAL) with stearoyl chloride at different molar ratios. The obtained polymers were characterized by means of 1 H NMR, transmission FT‐IR spectroscopy, differential scanning calorimetry and thermogravimetric analysis. The hydrophobic character of the film surfaces was investigated by IR‐ATR and by determining their surface and critical tensions. It was seen that it increased with increasing degree of substitution of the hydroxy groups of EVAL
