CA 2556157

Rigid polyurethane foams are described. The foams are made using a prepolymer that is the reaction product of at least one polyisocyanate component, at least one hydroxy-functional acrylate component, and at least one polyol component. The prepolymer is then reacted at specified volume ratios and isocyanate indices with at least one polyol component that includes at least one polyol that is a biopolymer, including but not limited to castor oil, soybean oil, and the like. The foam is made in the presence of at least one blowing agent and at least one catalyst.

L'invention concerne des mousses de polyuréthanne rigide, élaborées à partir d'un prépolymère qui est le produit de la réaction entre au moins une composante polyisocyanate, au moins une composante acrylate hydroxy fonctionnelle, et au moins une composnte polyol. Le prépolymère est ensuite soumis à réaction, selon des taux de volume et des indices d'isocyanate spécifiés, avec au moins une composante polyol comprenant au moins un polyol qui est un biopolymère, y compris mais pas seulement l'huile de ricin, l'huile de soja, etc. La mousse est établie en présence d'au moins un agent gonflant et d'au moins un catalyseur.
