Abstract
This invention relates to crosslinker sytems for polyurethanes and a process for producing such polyurethane products. The polyurethanes are prepared by reacting an organic polyisocyanate with an organic compound having active Zerewitinoff hydrogen atoms, e.g., a polyol with an alkoxylated diethyltoluenediamine crosslinker. Improved properties can be achieved, such as, higher load-bearing at equivalent density; higher tear; and higher elongation.
