ABSTRACT:
Relatively brittle epoxy resin systems which may be employed as structural film adhesives and matrix resins for fiber-reinforced prepregs are toughened against impact-induced damage by the addition of minor quantities of functionalized elastomer particles having a glass transition temperature of less than 10.degree. C.
