Use of stannous halide alcohol complexes, typified by the complex of stannous chloride and triethylene glycol, as catalysts permits production of urethane elastomers characterized by freedom from bubbles. The novel complexes are particularly characterized by their properties; e.g. Mossbauer spectra shows a chemical shift relative to a standard and a quadrupole splitting which are not found in mere mixtures of e.g., stannous chloride and triethylene glycol.
