Abstract (en)
[origin: WO2018087385A1] The present invention relates to a method for producing a polyurethane elastomer, comprising the reaction of at least one isocyanate composition (ZI) with a polyol composition (ZP) which contains a poly-e-caprolactone polyol and an a-hydro-ω-hydroxypoly(oxytetramethylene) polyol, thereby obtaining a isocyanate-group-containing prepolymer, and the reaction of the prepolymer obtained in step (i) with at least one chain extender (KV). The present invention further relates to a polyurethane elastomer obtainable or obtained according to a method according to the invention and to the use of a polyurethane according to the invention or of a polyurethane elastomer obtainable or obtained according to a method according to the invention for producing a molded article, especially a damping element, shock absorber or buffer stop or of a part of a shoe or a shoe sole, for example an insole or midsole.
