Abstract: Polyurethanes are made by curing a reaction mixture containing a polyether polyol that contains residues of a zinc hexacyanocobaltate catalyst complex. The reaction mixture contains certain chelating agents in small quantities. The amount of cobalt that is extractable from the polyurethane is reduced.
