Differential scanning calorimetric investigation of polymerisation of epoxy resin based on phenolphthalein with phthalic anhydride

Abstract

Abstract Polymerisation of phenolphthalein‐based epoxy resin with phthalic anhydride has been investigated by differential scanning calorimetry. The overall polymerisation kinetics were found to be independent of the concentration of phthalic anhydride and scan rate. The polymerisation was found to follow a simple Arrhenius‐type temperature dependence up to about 80% completion.
