Abstract

The modified poly (butylene succinate) (PBS), namely, PBS-g-MA and PBS-g-GMA were prepared in order to be used as a compatibilizer for PBS composites. The grafting of maleic anhydride (MA) or glycidyl methacrylate (GMA) onto PBS was carried out using a twin-screw extruder. The grafting reactions were confirmed by spectroscopic analysis. Comparing with MA, it was found that GMA can be effectively grafted on PBS. The PBS-g-GMA was successfully used for PBS composites to enhance thermal properties. Furthermore, it was found that the incorporation of compatibilizer increased the melt viscosity of PBS composites.
