Abstract:
The invention is directed to novel poly(ether-ester)polyols, processes for their production from monocarboxylic or polycarboxylic acid esters with one or more bound polyether chain(s). This invention also relates to the production of polyurethane materials in which the isocyanate-reactive component comprises these poly(ether-ester)polyols.
