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.

Abstract: The present invention is directed to a method for preparing a thermoplastic polyurethane having a low glass transition temperature. The process according to the present invention comprises the steps of providing at least one polyol composition (P) comprising a poly-ε-caprolactone polyol (P1), and a second polyol (P2) which is different from the first polyol (P1), and reacting the at least one polyol composition (P) with at least one polyisocyanate (P1) and at least one low molecular weight diol (CE) optionally in the presence of at least one catalyst (CA) and/or at least one additive (AD) to obtain a thermoplastic polyurethane. The present invention is also directed to the thermoplastic polyurethane obtained according to the process of the present invention and the use thereof in extruded articles and injection molded articles.
