ABSTRACT:
Tertiary amines having carbonate and urethane groups and optionally hydroxyl groups are produced by reacting a) a polyhydric alcohol and b) a primary-tertiary diamine with c) a carbonic acid derivative selected from the group consisting of optionally cyclic carbonates, urea, phosgene and bis-chlorocarbonates of alcohols of the same type as those used as component a). This reaction may be carried out in one or two steps. The tertiary amines produced by this process are useful as catalysts, which may optionally be incorporated into an isocyanate-reactive material, in the isocyanate addition reaction for the production of polyurethane plastics. These tertiary amines are particularly useful for the production of foam backed plastic films.
