Abstract
Novel thermosetting oligomers are formed by reacting epoxy prepolymers with aminoarylacetylenes. When heated to 170.degree. C. or above, these oligomers undergo acetylenic polymerization to form resins which exhibit superior thermal and hydrolytic stability when compared to conventionally cured epoxy resins.
