Abstract

Blends of PS/HDPE and PS/PP were investigated for synergism in flexural modulus with varying composition. The evolution of blend morphology was studied and related to the improvement in flexural modulus around the co-continuous composition. DSC studies were conducted to study crystallinity variations in the semi-crystalline component of the blend. We found that co-continuous morphologies help in developing strong mechanical bonds between the components. Crystallization is inhibited in the co-continuous region and is related to the spatial constraints during the solidification process.
