Rheological, Mechanical and Morphological Characterization of Monopolymer Blends Made by Virgin and Photo-Oxidized Polypropylene

In this work, monopolymer blends of virgin polypropylene and photo-oxidized were prepare characterized. The samples subjected to accelerated ageing simulate the effects outdoor exposure polypropylene. After exposure, pelletized mixed with same polymer. rheological, mechanical morphological characterization was conducted on both polymers blends. Both viscosity properties decrease increases in content recycled, components level degradation component. addition, experimental data compared a model that takes into account effect change molecular weight presence oxygenated groups.
