Abstract
Abstract This invention relates to polymeric polyols based on bis(hydroxymethyl)octadecanol with polybasic acids to make polyester polyols which have acid numbers less than about ten, and which polyester polyols are useful for a variety of known polyol applications as well as for making new urethane polymers which are advantageously useful in coatings, elastomers, adhesives, and caulking and sealing compositions or formulations.
