Abstract

Results of calorimetric (DSC) experiments on a series of poly (n-alkylmethcrylates), from methyl to pentyl, after different aging timeste at different aging temperaturesTe are presented. The aging behavior is quite different from that in other polymers, for example PS. For all poly(n-alkylmethacrylates) investigated the aging peak temperatureTmax is shifted parallel to the aging temperatureTe in a large temperature interval below the glass temperature. The results are discussed with respect to shear and entropy response in the αβ splitting region.
