Aromatic polyalkyleneoxy polyamines which are the reaction products of an aminocarbonyl, a polyalkyleneoxy polyamine, and aromatic diamines are useful in reaction injection molding processes to enhance the physical properties of the products produced. In addition, the polyamines of this invention are also useful as compatiblilizing agents in RIM systems to compatibilize mixtures of high molecular weight and low molecular weight polyols.
