Abstract

Cellular polyurethanes are obtained by jointly reacting polyethers having predominantly secondary hydroxyl groups with polyisocyanates and water in the presence of a non-basic metal salt or a non-basic organo metallic compound. Lists of suitable reactants are given. Optional ingredients are emulsifiers; stabilizers, e.g. silicone oils; dyes; flame proofers; fillers; plasticizers; pore regulators and the known catalysts, e.g. tertiary amines. Specifications 769,680, 769,682, 843,841 and 867,156 are referred to.ALSO:Cellular polyurethanes are obtained by jointly reacting polyethers with predominantly secondary hydroxyl groups, polyisocyanates and water in the presence of a non-basic metal salt or a non basic organometallic compound.
