Influence of Polymer Blending on Mechanical and Thermal Properties

Buthaina A. Ibrahim, Karrer M.Kadum


Polymer blends are capable of providing materials with extended useful properties beyond the range that can be obtained from single polymer equivalents. Blends of polystyrene (PS) and Acrylonitrile-Butadiene-Styrene (ABS) are prepared in different ratios by melt blending technique which was carried out using a single screw extruder. The tensile test and Differential Scanning Calorimetry (DSC) are used to study mechanical and thermal properties. The results from this work show that the mechanical properties for blend system are better than those of pure polymers, also the (DSC) test gives good indications of improving state of miscibility for most blend ratios; there is only one glass transition temperature between the two values of pure polymers.
