摘要：

Melt blends of nylon with poly(styrene-co-maleic anhydride) (SMA) were prepared in a twin-screw extruder. Viscoelastic properties of the melt and morphological, thermal, and mechanical properties of the blends were determined. Fourier-transform infrared (FTIR) spectroscopy measurement indicated reactions between nylon and SMA. Melting peak temperature (T(m)) of nylon was not changed in blends. This, together with the FTIR results, assured that the reactions occur mainly with the free amide end groups of nylon. Melt viscosity, elasticity, and the heat-distortion temperature (HDT) of nylon was significantly increased with the addition of SMA. Tensile strength and impact strength of nylon were, respectively, in general, increased and decreased with SMA.
