Abstract
Alkoxylated polyester polyols useful in the manufacture of polyurethanes are disclosed. For example, 9(10)-methylhydroxymethyloctadecanoate can be reacted with bishydroxymethyltricyclodecane to prepare a polyester polyol which can be ethoxylated to prepare an alkoxylated polyester polyol. The resulting polyester polyol can be reacted with a diisocyanate, such as a modified diphenylmethane diisocyanate, to prepare a urethane elastomer.
