Curable impact modified epoxy resin having stabilized multiphase morphology

摘要

A curable impact modified epoxy resin mixture suitable for producing high performance composites is composed of A. an aromatic epoxy compound, B. an amine type curing agent, C. from 10 to 40% by weight of an aromatic thermoplastic oligomer which contains reactive groups, preferably a polyether sulfone, and 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.
