In this work, properties of ABS/AES blends were investigated. Blends were prepared by casting from THF. The thermal stability, light resistance, storage modulus and flame retardancy were measured by thermogravimetric analysis, color difference in Fade-o-meter, Rheovibron, and limiting oxygen index(LOI). The thermal stability, light resistance and storage modulus increased with increasing contents of AES. ABS and AES showed similar LOI. The LOI of the ABS/AES blends increased with rising contents of AES but all the blends were found to be flammable. It was observed that ABS and AES was incompatible from the morphology by scanning electron microscope(SEM).

The structure and properties of blends of ethylene-propylene-diene terpolymer(EPDM) and polyolefin blends have been investigated. The theology and tensile properties of the EPDM/HDPE(high density polyethylene), EPDM/PP(polypropylene) binary and EPDM/PP/HDPE ternary blends were studied along with morphological analyses. Those properties were affected by preferential interaction of EPDM on HDPE, compared to that of EPDM on PP, for the binary blends. The preferetial interaction may stem from the molecular characteristics of EPDM to possess more ethylene units than propylene units in the elastomer. The EPDM played a role as compatibilizer for HDPE and PP in the EPDM/PP/HDPE ternary blends.
