摘要：

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