Abstract
Polycarbonate (PC) and poly(acrylonitrile-butadiene-styrene) (ABS) was co-extruded at different weight ratios by a single screw extruder. In order to obtain a finer blend, two times extrusion was carried out. I n this case, a ''network'' structure with two-continuous phases was ob served for the blends with two compositions of PC/ABS, being 80/20 and 70/30. It is found that the blends with these two compositions just h ave maximum values on the curves of notched Izod impact strength, flex ural modulus and flexural strength vs. composition, respectively. This was never observed in previous publications.
