Abstract

Polymer blends containing poly(acrylonitrile-butadiene-styrene) (ABS) and polycarbonate (PC) (70/30, wt%) with compatibilizer were prepared using twin screw extruder. Compatibilizers were prepared by reactive extrusion with the ABS, maleic anhydride (MAH) and dicumyl peroxide (DCP) using twin screw extruder. In the ABS/PC (70/30) blends, tensile strength did not change significantly, but increased from 52.25 to 55.03 MPa when the ABS-g-MAH was added in the amount of 5 phr. From the results of rheological properties, storage modulus of the ABS/PC/ABS-g-MAH blends at low frequencies showed lager value than that of the ABS/PC (70/30) blend. From the results of the morphological properties of the ABS/PC (70/30) blend, it was observed that the drop size of the PC ranged from 1.2 to 1.5 μm and did not change significantly with the addition of the ABS-g-MAH(1∼10 phr). From the results of the storage modulus, complex viscosity, and tensile strength of the ABS/PC (70/30) blends, it is found that the ABS-g-MAH is an effective compatibilizer in the ABS/PC (70/30) blends when the ABS-g-MAH is added in the amount of 5 phr.
