dc.description.abstractNatural weathering degradation of the blends of recycled polypropylene (PPr) with Polystyrene (PS), Polyvinyl chloride (PVC) and Virgin Polypropylene (PPv) was studied. Film samples of 25 by 1.5 by 0.02Cm3.PS, PVC and PPv were blended with PPr for the purpose of improving its mechanical properties, which was generally considered as inferior. While no particular blends had over all good result of all the mechanical Properties tested, however, PS/PPr produced the best result of tensile strength, followed by the blends of PPv/PPr and PVC/PPr. The blend of PPv/PPr had the highest elongation followed by the blends of PVC and PS. The young modulus results show that at 20%, the PS blends has the highest young modulus. Also PS blend resist embrittlement more than PPv and PVC blends. In summary the blends of PS and PPr at ratio 20:80 is considered good enough to improve the mechanical properties of recycled polypropylene better than the other blends.en_US
