Abstract
An ungelled composition is prepared as the half-amide reaction product of a diester of oxalic acid and a material containing one or more primary and/or secondary amino groups and one or more different functional groups. The ungelled composition is useful as a crosslinking agent for amine group containing materials and as an intermediate in the preparation of resinous compositions for fire protective coatings.
