摘要：

Crosslinking reactions between epoxy and carboxylic groups in the presence of an activator (triethylamine, TEA) have been studied. The epoxy compound was diglycidylether Bisphenol A (DGEBA) and hardeners were either random poly(styrene-co-acrylic) copolymers, polyacrylic acid (PAA) or an alternating maleic anhydride/styrene copolymer. Reactions were followed using a DSC technique in a dynamic mode between 25 and 250 degrees C at different heating rates (2.5, 5, 7.5, 10, 15 and 20 degrees C/min). Crosslinking reactions followed second order kinetics. Arrhenius parameters were determined. (C) 1997 Elsevier Science Ltd.
