Abstract

The present invention is directed to polyhydroxyl compounds containing both ether and ester groups, having an average hydroxyl functionality of 2 to 6 and an average hydroxyl number of about 100 to 600, based on the esterification product of (i) polyether polyols having an average hydroxyl functionality of 3 to 8 and an average hydroxyl number of about 200 to 1000 with (ii) about 5 to 70 equivalent %, based on the hydroxyl group of component (i) and the carboxyl group of component (ii), of organic monocarboxylic acids. The present invention is also directed to the use of the polyhydroxyl compounds as synthesis components in the production of polyurethane plastics materials by the isocyanate-polyaddition process, particularly their use as the polyol component in two-component polyurethane coating agents and/or polyurethane casting systems which are solvent-free or have a low solvent content.
