| Abstract: | Poly(trimethylene terephthalate)/acrylonitrile-butadiene-styrene(PTT/ABS) blends were prepared by twin screw extruder.The effects of blends composition and compatibilizer epoxy as well as styrene-butadiene-maleic anhydride copolymer(SBM) on phase morphologies and mechanical properties of the blends were investigated.The results showed that the uncompatibilized blends exhibited coarse morphologies showing sharp phase boundaries.The tensile and flexural strengths decreased whereas the impact strength increased with the increasing of the ABS content.The epoxy or SBM incorporated blends showed finer morphologies and the interfacial adhesion were improved.Moreover,the tensile and flexural strength increased whereas the impact strength remained unchanged. |
