Abstract
Blends of polycarbonate/acrylonitrile-butadiene-styrene terpolymer (PC/ABS) and polycarbonate/maleic anhydride grafted ABS (PC/MABS) were prepared over the whole range of compositions using a single-screw extruder. Tensile, flexural, notched Izod impact properties, and the heat deflection temperature of these blends were determined. Mechanical properties of PC/MABS blends are nearly equal to or higher than, those predicted by the rule of mixtures, whilst those of PC/ABS blends show nearly equal, or negative deviation, from the rule of mixtures. The notched impact strength of PC/MABS blends shows a positive blending effect and proportionate increase from 25wt% PC to 75wt% PC. Scanning electron micrographs were taken of etched surfaces of selective blends. ©1998 SCI.
