Abstract

Polypropylene (PP) is a thermoplastic polymer used as packaging for alcoholic and nonalcoholic beverages bottles, detergent and cosmetics, bags, transparent packaging for food and non-food industrial products, pipes, fittings and other applications. In this paper, wastes of PP resulted from textile cones were modified with poly (styrene-isoprene-styrene) (SIS). Recycled PP/SIS composites containing 0, 5, 10, 15, 20, 25 and 30 weight % of SIS were performed by melt alloying technique. By varying of SIS content can be tailored composites able to meet the service requirements when PP is used as recycled materials for specific end use applications. It is found that new developed composites show a good elasticity and notched impact IZOD compared with unmodified PP wastes and are suitable for industry field, e.g. automotive parts..
