Abstract
Enthalpic ageing data for poly(methyl methacrylate) are reanalysed in terms of a modified version of the Cowie-Ferguson model which takes ac count of a time-dependent characteristic time, t(c). In terms of descr ibing the time evolution of enthalpy changes occurring upon ageing, no significant improvement in the fits to the data were found when compa red with the original linear model.
