The Role of Compatibilizers on the Properties of PC/ABS Alloy
Abstract: Two compatibilizers consisting of styrene-acrylonitrile-glycidyl methacrylate (SAG) terpolymer with different contents of glycidyl methacrylate (GMA), SAG-001 (1 wt% of GMA) and SAG-005 (5 wt% of GMA), and styrene-acry-lonitrile-maleic anhydride terpolymer (SAM), SAM-002 (2 wt% of maleic anhydride ), were used to evaluate the role of compatibilizers in the PC/ABS alloy in terms of the mechanical properties, thermal stability and phase morphology. The tensile strength of SAG modified PC/ABS alloy slightly increased than that of SAM modified system, but the two compatibilizers barely affected the flexural strength of the system. On the other hand, the impact strength of SAG modified PC/ABS was improved. In addition, the MFR (melt flow index) of the SAG modified PC/ABS alloy reduced, implying that the viscosity or molecular weight of the system increased. The HDT (heat distortion temperature) also improved with SAG modified system. Moreover, the phase morphology of the SAG modified PC/ABS alloys much enhanced than that of SAM modified system. As a consequence, SAG compatibilized PC/ABS alloy showed better properties than those of SAM modified system, suggesting that the reaction between carboxylic or epoxy groups in SAG and terminal carboxyl group in PC would be the main factor to bring the enhancement in the mechanical, thermal and morphological properties of the PC/ABS alloy.
