The concept of modifying epoxy resins with carboxyl‐reactive butadiene‐acrylonitrile liquid and solid elastomers has been extensively documented in the last 10–15 years in the open literature. Review articles by this author and R. S. Drake have appeared over the last 10 years describing this work. More recently, amine‐reactive butadiene‐acrylonitrile liquid copolymers were developed as modifiers for two part epoxy systems under ambient or slightly elevated temperature cure conditions. Much of the work described in the open literature centers on the mechanisms by which these two‐phase systems work and their utility in structural adhesives. However, these modified epoxies also find utility as matrix resins in composites. This paper will be a review of the open journal and patent literature on the use of the carboxyl and amine‐reactive elastomer‐modified epoxies as matrix resins for composites. It will deal with the theoretical aspects of that work as well as describing and showing practical composite applications for these systems.
