ABSTRACT:
Polyurethane molding compositions are disclosed which contain diisocyanates and polyols and/or polyurethane prepolymers and sorbic acid or cinnamic as a setting catalyst. A process for preparing such compositions is also disclosed. These compositions give a rapid initial hardening and therefore mold release properties, which contribute to increased production speeds. Moreover, the acids used are physiologically safe, so that the process may be used for the production of objects used in medical science. The acids may also be used in a physiologically safe mixture with a heavy-metal containing catalyst.
