The effect of dynamic vulcanization on mechanical, rheological, thermal properties and morphology of ABS were studied in this paper. And the effect of shear stress, shear rate on melt rheological behavior were discussed. The results showed that: the melt of dynamic vulcanization modified ABS was pseudoplastic fluid, and its apparent viscosity was increased. Tensile strength, notched impact strength of dynamic vulcanization modified ABS increased gradually, and the melt flow rate decreased gradually . |
