Abstract:
Disclosed are high strength polyurethane foam compositions and methods of making them. In one aspect, the inventive polyurethane foams include strength enhancing additives comprising one or more polycarbonate polyols derived from the copolymerization of CO 2  and one or more epoxides. In one aspect, the inventive methods include the step of substituting a portion of the polyether polyol in the B-side of a foam formulation with one or more polycarbonate polyols derived from the copolymerization of CO 2  and one or more epoxides.

Claim (Index 30):
A method for increasing the strength of a polyurethane foam composition, the foam composition comprising the reaction product of a polyol component and a polyisocyanate component, the method comprising the step of incorporating into the polyol component a polycarbonate polyol derived from the copolymerization of one or more epoxides and carbon dioxide, wherein the polycarbonate polyol is added in a quantity from about 2 weight percent to about 50 weight percent, from about 5 weight percent to about 25 weight percent, from about 2 weight percent to about 10 weight percent, from about 10 weight percent to about 20 weight percent, from about 20 weight percent to about 30 weight percent, or from about 30 weight percent to about 50 weight percent of all polyols present in the polyol component;\n wherein a tear strength value measured by ASTM D 3574-08 of the foam composition comprising the added polycarbonate polyol is greater than the tear strength value of a corresponding foam composition formulated without the added polycarbonate polyol.
