Abstract

Differential Scanning Calorimetry (DSC) and Thermogravimetric Analysis (TGA) of .poly(methacrylates) containing indanyl moieties were performed. Different Tg-Mn relationships have been established in order to obtain the glass transition temperature in the limit of high molecular weight Tg? using samples of different number average molecular weight (Mn). Non linear dependence between Tg and Mn using different relationships is found. The values of Tg? is correlated with the chain rigidity parameters for these polymers. Thermogravimetric analysis shows different degradation profiles depending on the structure of the side chain of the polymer.
