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