Abstract

Low temperature flexible polyurethane elastomers are prepared by reacting organic polyisocyanates with polyester polyols which have glass transition temperatures of -10.degree. to -80.degree. C. and incorporating therein alkoxylated esters of fatty acids and/or alkoxylated terpene alcohols.
