Abstract
Crosslinking reactions between epoxy and carboxylic groups in the pres ence of an activator (triethylamine, TEA) have been studied. The epoxy compound was diglycidylether Bisphenol A (DGEBA) and hardeners were e ither random poly(styrene-co-acrylic) copolymers, polyacrylic acid (PA A) or an alternating maleic anhydride/styrene copolymer. Reactions wer e 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 degre es C/min). Crosslinking reactions followed second order kinetics. Arrh enius parameters were determined. (C) 1997 Elsevier Science Ltd.
