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.

L'invention concerne des prépolymères préparés par réaction d'un polyisocyanate et d'un polyol de polyester contenant de l'hydroxyméthyle dérivé d'un acide gras. On peut préparer ces prépolymères en ayant des groupes isocyanate, hydroxyle ou une variété d'autres groupes fonctionnels réactifs. Ces prépolymères peuvent servir à fabriquer des polyuréthanes et d'autres polymères, ou des agents de réticulation.
