    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.

    Abstract: The present invention relates to a polyurethane, in particular a thermoplastic polyurethane, obtainable or obtained by reacting at least the components (i) to (ii): (i) a polyisocyanate composition; (ii) a polyol composition, comprising (ii.1) at least one polyester diol or polyether diol having a number-average molecular weight in the range from 500 to 3000 g/mol, (ii.2) at least one polysiloxane having two terminal isocyanate-reactive functionalities selected from the group consisting of thio group, hydroxyl group and amino group. The invention additionally relates to a process for preparing this polyurethane, to the use thereof, to a molded body comprising the polyurethane. Furthermore, the invention relates to foam beads based on polyurethane, obtained or obtainable from the polyurethane, to a process for producing foam beads and also to bead foams and to the use thereof.

    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.
