Abstract

Epoxy resins contain a discontinuous phase dispersed therein, of grafted rubber particles having an insoluble rubber core and having a grafted shell containing a functionalized compound such as that provided by polymerized glycidyl methacrylate, which is reactive under curing conditions with a functionality of the epoxy resin phase. The dispersions are stable and are useful as curable coatings, and for providing toughened resins for structural applications.
