This invention relates to a process for producing solid and microcellular polyether polyurethane elastomers by rapid processing technology wherein the resulting elastomers have improved "green strength" (cracking resistance). In the process, dialkyltin dimercaptide carboxylic acid ester is employed as the sole urethane catalyst in higher-than-normal amounts. The process is particularly suitable for use in the rapid processing technology known as Reaction Injection Molding (RIM).
