Abstract
Cured products are produced by heating novel 1-arylcyclobutenecarboxylate ester derivatives of N-glycidylamine compounds. The cured products are obtained by applying heat to the ester derivatives, in the presence of or in the absence of added curing agent, and the cured products are crosslinked insoluble solid materials having useful properties characteristic of thermoset polymers.
Claims18
A cured, crosslinked product obtained by heating to a temperature above 150.degree. C. a 1-arylcyclobutenecarboxylate ester of a N-glycidyl compound wherein the arylcyclobutene moiety has up to 4 aromatic rings and up to 30 carbon atoms, inclusive, and has at least one cyclobutene ring fused to an aromatic ring, and the N-glycidyl compound has up to 4 rings and up to 30 carbon atoms, inclusive, has at least one amino nitrogen and at least two glycidyl groups attached to amino nitrogen atoms.
