Abstract: Spent polyurethanes are returned to the value chain by hydrogenating the spent polyurethanes in a hydrogen atmosphere in the presence of at least one homogeneous transition metal catalyst complex, wherein the transition metal is selected from metals of groups 7, 8, 9 and 10 of the periodic table of elements according to IUPAC, to obtain a polyamine and a polyol. The hydrogenation is carried out at a reaction temperature of at least 120° C. in a non-reducible solvent having a dipole moment of 10-1030 C·m or less.

Abstract: Described herein is a process for preparing a foam (FA) with a Poisson's ratio in the range of from −0.5 to 0.3, the method including the steps of providing a foam (F1) with a flow resistance in the range of from 3000 to 8000 Pas/m, determined according to DIN EN 29053, and subjecting the foam (F1) to thermoforming including triaxial compression, wherein the foam (F1) is not reticulated prior to step (ii). Also described herein is the foam obtained or obtainable according to the process and the use of the foam as, for example, an energy absorbing device, preferably in protective gear, furniture, cushions, in cleaning devices with improved rinse-out behavior, in shoe soles, or as sealing, insulating or anchorage providing material for example used in earphones, ear plugs or dowels, or as acoustic material.
