Abstract
Acrylonitrile-butadiene-styrene (ABS) high-rubber powder (HRP) toughened acrylonitrile-butadiene-styrene (ABS)/polymethyl methacrylate (PMMA) blends were prepared in a co-rotating twin screw extruder. The effect of ABS HRP on mechanical and morphology properties of ABS/PMMA blends was studied. It is shown that the toughness of ABS/PMMA blends was improved effectively with the incorporation of ABS HRP, while the elastic modulus and tensile strength decrease slightly. Tensile tests at different strain rates were carried out in order to investigate the influence of strain rate on mechanical properties of various blends. Finally, the strain rate sensitive behavior of different blends was explored by using the Eyring model.
