Acrylonitrile-butadiene-styrene, acidic pumice, polymer composites,thermoplastic polymers, polymer processing

The improvement of physical, thermal, rheological properties of acrylonitrilebutadiene-styrene polymers is still great interest of researches due to the largeapplications areas. In this work, acrylonitrile-butadiene-styrene matrix and acidicpumice particles were mixed in order to obtain composites. The compositepreparations were achieved by using co-rotating twin-screw micro-compounder andthe test specimens were obtained by injection-molding device.The feeding ratios of acidic pumice particles were chosen 5%, 10%, 15%, and 20%respectively. The characterizations of prepared composites were performed by tensiletest, impact test, melt flow index measurement, dynamic mechanical analysis andscanning electron microscopy methods.According to test results, the maximum improvements were observed for 15%addition of AP among the composites. This composition was remarked as the mostsuitable for ABS/AP composites.
