Abstract
Pure polystyrene-b-poly(ethylene-ran-butylene)-b-polystyrene (SEBS) was functionalized with amine moiety first through nitration, followed by reduction. The resulting amine modified SEBS was blended with various amounts of epoxy via in situ reactive approach. Thin blend films were initially cured at 120 ℃ for 30min and post cured at 180 ℃ for 2 h. These films were then analyzed for their mechanical, thermal and morphological profile. Optimum improvement in tensile strength, modulus and toughness was observed with different epoxy loading in the blends. These blends_x000D_
were found thermally stable up to 300 ℃. The morphological studies indicated ample compatibility between the two components of blends.
