Abstract
This invention relates to a process for the production of optionally cellular, elastic, shaped articles having an impervious surface layer of polyurethane-polyurea elastomers by reacting a reaction mixture of organic polyisocyanate, ethylene oxide-tipped polyoxyalkylene polyols, propylene oxide-tipped polyoxyalkylene polyols, catalysts, amine chain extenders and optionally surfactants and blowing agents by the reaction injection molding (RIM) technique.
