EFFECT OF SEBS COPOLYMER IN MECHANICAL AND THERMAL PROPERTIES OF PP/PA6 POLYMER BLENDS

ABSTRACT In this study, an incompatible blend of PP and PA 6 has been made compatible by the addition of 10% SEBS. The mixing operation was conducted by using a twin- screw extruder. The compatibility of the mixtures was examined by using DSC technigue. Furthermore, the elastic modulus, tensile and yield strengths, percent elongation, hardness, melt flow index, izod impact energy values of the polymer alloys of various ratios were determined.   Key Words: Copolymer, polymer alloys, compatibilizer , mixture, sebs,extrusion.
