ABSTRACT:
Thermoplastically processable polyurethane elastomers are prepared by A) mixing one or more substantially linear polyols with a diisocyanate, B) reacting the resultant mixture substantially completely in a reactor at temperatures of >100.degree. C. to form a prepolymer, C) mixing the prepolymer with low molecular weight chain extenders, D) applying the reaction mixture prepared in stage C) to a support and allowing the mixture to react thereon to solidification.
