POLYETHERESTER POLYOLS AND USE THEREOF FOR PRODUCING POLYURETHANE HARD FOAM MATERIALS

摘要

The invention relates to a polyetherester polyol comprising the conversion product of a1) 5 to 63 wt% of one or more polyols or polyamines or mixtures thereof having an average functionality of 2.5 to 8, a2) 2 to 50 wt% of one or more fatty acids, fatty acid monoesters or mixtures thereof, and a3) 35 to 70 wt% of one or more alkylene oxides having 2 to 4 C-atoms.
