Abstract
The invention relates to dioxomolybdenum (VI) complex compounds of the formula MoO2(L)x(Y)2-x, where the ligand L has the formula (I). Such complex compounds are suitable in particular as catalysts for one- and two-component polyurethane compositions. The invention also relates to two-component polyurethane compositions including at least one polyisocyanate as the first component, at least one polyol as the second component, and at least one such dioxomolybdenum (VI) complex compound as the catalyst. The invention further relates to one-component polyurethane compositions comprising at least one polyurethane prepolymer with isocyanate groups, which are made from at least one polyisocyanate with at least one polyol, and comprising such a dioxomolybdenum (VI) complex compound as the catalyst. The invention additionally relates to different uses of said polyurethane compositions.
