Styrene-block-ethylene butylene-block-Styrene (SEBS) with Ethylene-Vinyl Acetate (EVA) copolymer blends were prepared by melt and solution mixing methods. Compatibility of these blends has been examined by using solution viscometry, thermal, morphological and mechanical analysis technigues. In order to evaluate the compatibility, Krigbaum & Wall's Delta b parameters were calculated. It was obtained that weight wise ratios of 50/50, 70/30 and 90/10 SEBS/EVA blends were found to be compatible. Thus indicates that compatibility increases with increasing SEBS ratio in the blend. Differantial scanning calorimetry curves of SEBS/EVA blends at the compositions of 50/50, 70/30 and 90/10 showed a single T-g value between -60 degrees C and -30 degrees C. Morphology of the blends were investigated by scanning electron microscopy (SEM). There was no observable phase separation for all blend composition.
