Blends of polycarbonate (PC) and acrylonitrile-butadiene-styrene (ABS) were prepared and some mechanical, morphological properties and thermal stability were investigated. We selected the ratio of 80/20 to prepare PC/ABS alloys. Two kinds of compatibilizers, methacrylate-butadiene-styrene (MBS) and styrene-maleic anhydride (SMA) were used to improve the compatibility between PC and ABS. The results showed that SMA had no significant effect on the tensile strength of the blends while MBS decreased the tensile strength of blends a lot. Results of notched charpy impact strength tests showed that SMA increased the impact strength of blends more than MBS. The maximum increase was about 36.4 % when using 15wt% of SMA. Scanning electron microscopy micrographs showed that the particle size of ABS was decreased in the continuous phase of PC by using the compatibilizers. Moreover, differential scanning calorimetry (DSC) curves proved both MBS and SMA could make the glass transition temperature (Tg) of two phase close to each other. Finally, thermogravimetric tests showed that MBS and SMA had little effect on thermal stability of the PC/ABS blend.
