Popis: Blends of ethylene propylene diene rubber (EPDM) and thermoplastic polyurethane (TPU) have been studied to understand the compatibility and morphology. The study was initially done with unmodified EPDM and subsequently with modified EPDM through maleation process. Mechanical properties of unmodified EPDM blends are improved with the addition of TPU. However, the appearance of two T gs even at lower concentrations of PU in the blends indicates that the blends are incompatible. Blends of maleated EPDM with TPU showed a single T g and further improvement in mechanical properties which is attributed to the improvement in compatibility as also confirmed by SEM analysis.
