The present invention relates to a process for the catalytic preparation of polyetherols, wherein the power input by means of at least one stirrer and/or by means of at least one pump, based on the reactor volume, is in the range from 0.001 to 8.2 kW/m.

Process for preparing polyether polyols

The invention relates to mixtures (1) comprising (a) polytetrahydrofuran and (b) stabilizers having a molecular weight of from 600 g/mol to 10000 g/mol and comprising at least two phenolic groups.

Mixtures containing polytetrahydrofuran and a stabiliser

Diisocyanates containing hydantoin groups and polyurethanes in which they are present

Highly functionalized polyurethanes

A process for decoloring polyisocyanates containing isocyanurate and uretdione groups comprises treating the demonomerized polyisocyanates containing isocyanurate and uretdione groups with oxygen.
