ABSTRACT:
An epoxy resin composition is disclosed. The composition comprises a polyepoxide and a curing amount of a bis(hydrogen maleate) derivative of a polyoxypropylenediamine. This composition when cured produces unexpectedly superior encapsulations which are more flexible and less brittle than those of the prior art.
