摘要：Use of fatty acids and their derivatives in preparing amine type curing agents for epoxies was explored in this study. Dicarboxylic (C21) acids were prepared through addition reaction of esters of tung oil fatty aids and acrylic acid. The C21 acids were then reacted with polyamines to yield polyamidoamine type curing agents. The flexible hydrocarbon chains of fatty acids were also introduced to the Mannich base type curing agents for improved impact strength. Derivatives of fatty alcohols were used to prepare curing agents for waterborne epoxies. Furthermore, polyamidoamines based on rosin modified dimer fatty acids were also prepared. The properties of epoxies cured with these curing agents were evaluated. ? 2012 American Chemical Society.
