Abstract: The present invention relates to a method of preparing a polyurethane elastomer. The method includes a step of reacting at least one isocyanate composition and one polyol composition containing a poly-ε-caprolactone polyol obtained by reacting ε caprolactone and a diol having a number average molecular weight of from 80 to 1500 g/mol to obtain an isocyanate-functional prepolymer; and a step of reacting the prepolymer with at least one chain extender. The polyol composition contains α-hydro-ω-hydroxypoly(oxytetramethylene) polyols in an amount ranging from 0 to 1 wt % based on the entire polyol composition. The present invention further relates to a polyurethane elastomer prepared by such a method and also to the use of the polyurethane elastomer in the manufacture of a shaped article, especially a damping element, a shock absorber, a stop buffer, or a part of a shoe, such as a shoe sole, in particular, an insert sole or a midsole.

Abstract: Described herein is a process for producing a polyurethane foam including mixing (a) polyisocyanate, (b) polymeric compounds having isocyanate-reactive groups, (c) silicone-free stabilizer, (d) optionally chain extending and/or crosslinking agents, (e) catalysts, (f) blowing agents, and (g) optionally auxiliaries and additives to afford a reaction mixture and reacting the reaction mixture to afford the polyurethane foam. Also described herein are a polyol component including the silicone-free stabilizer (c), a polyurethane foam obtained by the process, and a method of using the polyurethane foam in enclosed spaces or in the interior of vehicles.

Abstract: The present invention relates to a method of preparing a polyurethane elastomer, said method comprising the step of reacting at least one isocyanate composition (ZI) and one polyol composition (ZP) comprising a poly-ε-caprolactone polyol and an α-hydro-ω-hydroxy-poly(oxytetramethylene) polyol to obtain an isocyanate-functional prepolymer and the step of reacting the prepolymer obtained as per step (i) with at least one chain extender (KV). The present invention further relates to a polyurethane elastomer obtained or obtainable according to a method of the invention and also to the method of using a polyurethane elastomer according to the invention or a polyurethane elastomer obtained or obtainable according to a method of the invention in the manufacture of a shaped article, especially a damping element, a shock absorber or a stop buffer or part of a shoe or of a shoe sole, for example part of an insert sole or of a midsole.
