Homopolymers and Polymer Blends

In the Master s dissertation entitled Effect of natural and accelerated ageing on the properties of PET/PC (80/20) blend , recycled polyethylene terephthalate (rPET) was blended with PC (80/20 wt/wt), and then submitted to natural ageing in the city of Rio de Janeiro [17]. For comparison purposes, we also monitored the accelerated ageing of the blend in an appropriate chamber under the same conditions, 2,000 h of exposure were performed. The Fourier-Transform infrared spectroscopy revealed the tendency of the PET and PC carbonyl indices to decrease upon an increase in
