Ternary PC/ABS/PMMA blends — morphology and mechanical properties under
quasi-static loading conditions (in English)
Polimery 2012, No 2, 87
PC/ABS/PMMA blends with a varied content of PMMA were studied. TEM microscopy was employed to reveal the individual phases. Uniaxial tensile testing and instrumented macro-hardness indentation were carried out to quantify the hardness, indentation modulus, elastic and plastic deformation work during indentation, yield strain and stress values. The data was correlated with the morphology. In case PMMA is the minor phase, it tends to locate on the PC/SAN interface; whereas in case of being the major one, SAN plays the role of compatibilizer and encapsulates the PC particles. Good compatibility of the blends was confirmed by the results of mechanical testing, which revealed strain-controlled plasticity.
