C.The compounds are finely dispersed with an average particle size of not less than 5 to 100.mu. in amounts of 0.5 to 5 weight percent, based on the reaction formulation. The release agents are preferably suspended in a portion of the polyol or polyolamine that is to be foamed.The release agents exhibit outstanding release properties and, in the event that molded polyurethane or polyurea articles with a cellular core are prepared, do not prevent the development and/or the maintenance of the cellular structure.
