Abstract

The effect of impact modifier ACR of nuclear-shell structure on the mechanical properties and heat resistance of PC/PBT (80/20) blend system was studied,and the morphology of the blend system was observed by means of SEM.The result showed that the Izod notched impact strength of the blend system increased first,and when ACR content was up to 15 phr,the Izod notched impact strength was the maximum,while the tensile strength and Vicat softening point(VSP) of the system decreased.
