Abstract
A method of imparting internal mold release properties to reaction injection molding polyurethane compositions by the addition of a perfluoroalkylorganocarboxylic acid or a salt thereof. This invention also relates to the production of novel perfluoroalkylorganodibutyltindioxide compounds which are inherently catalytic and can also impart the property of internal mold releasability to RIM compositions.
