Abstract
Prepolymers are prepared by a reaction of a polyisocyanate and a hydroxylmethyl containing polyester polyol derived from a fatty acid. The prepolymers can be prepared having isocyanate, hydroxyl, or a variety of other reactive functional groups. The prepolymers are useful in making polyurethanes and other polymers, or a crosslinking agents.
