The effect of accelerated degradation on the Mw of a PVC object. The difference in Mw for an object after and before accelerated degradation is plotted and compared against two standard deviations (± 4500 g/mol). The conditions and time of accelerated degradation are presented in the legend, with the time of degradation expressed in weeks (w)
