Abstract

A curable impact modified epoxy resin mixture suitable for producing high performance composites is composed of PA0 A. an aromatic epoxy compound, PA0 B. an amine type curing agent, PA0 C. from 10 to 40% by weight of an aromatic thermoplastic oligomer which contains reactive groups, preferably a polyether sulfone, and PA0 D. from 0.1 to 10% by weight of a high molecular weight emulsifier, preferably a phenoxy resin, an epoxy resin or a thermoplastic copolymer, which is compatible not only with the epoxy compound A but also with oligomer C.
