Abstract
The effects of different acrylic rubber (PBA) contents in core-shell structured rubbery acrylate-g-poly (styrene-acrylonitrile) (PBA-SAN) on the mechanical properties of PBA-SAN and PBA-SAN/SAN blends were systematically investigated. Fourier transform-infrared spectroscopy (FTIR) and scanning electron microscope (SEM) were used to characterize the structure and morphology of PBA-SAN and PBA-SAN/SAN blends, respectively. It was found that the mechanical properties of PBA-SAN and PBA-SAN/SAN blends strongly depended on the PBA content: largely improved impact strength and elongation at break were observed when adding PBA-SAN with high PBA content. However, the loss in rigidity and heat distortion temperature were accompanied. Specifically, both PBA-SAN and PBA-SAN/SAN blends with 60 wt% PBA exhibited a good balance between toughness and rigidity, which indicating PBA-SAN with 60 wt% PBA was the most suitable impact modifier.
