Abstract
Novel carbamic and carbonic acid derivatives are provided by simultaneous reaction of a secondary amine and a tertiary amine with carbon dioxide. These derivatives correspond in general to the formula ##STR1## in which R.sub.1 and R.sub.2 may be individual substituents attached to the N or together form with N a heterocyclic moiety; R.sub.3, R.sub.4, R.sub.5 may be individual short chain alkyl or hydroxyalkyl substituents on the N or form therewith a monocyclic or bicyclic heterocyclic moiety. These described compounds find particular use as heat activatable delayed action catalysts especially for use in polyurethane formulations.
