Abstract
In this work, acrylonitrile-styrene-acrylic terpolymer/styrene-acrylonitrile copolymer/hydrogenated nitrile rubber (ASA/SAN/HNBR) ternary blends with different composition were prepared by melt blending. Properties of the ternary blends were studied by differential scanning calorimetry (DSC), dynamic mechanical analysis (DMTA), Fourier transform infrared spectra (FTIR), heat distortion temperature (HDT), melt flow rate (MFR), and Scanning electron microscopy (SEM). The results showed that the incorporation of HNBR can enhance the toughness by a large scale, and the two rubber phase showed partial miscibility. Heat resistance of the blends almost unchanged with HNBR content. FTIR told that the preparation of the ternary blends was a physical process, and no obvious phase separation was observed in SEM images.
