Abstract
A reaction injection molding (RIM) process for making polyurethanes is disclosed where in addition to the conventional ingredients such as polyols, isocyanates, and catalysts there is included a carboxy functional siloxane. The incorporation of the carboxy functional siloxane aids in the release of the molded part and shortening the molding cycle time.
