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 43):
The method of  claim 40 , wherein the polycarbonate polyol is characterized in that it has an Mn between about 500 g/mol and about 20,000 g/mol, between about 1,000 g/mol and about 5,000 g/mol, between about 1,000 g/mol and about 3,000 g/mol, or between about 1,000 g/mol and about 3,000 g/mol, or an Mn of about 1,000 g/mol, about 1,200 g/mol, about 1,500 g/mol, about 2,000 g/mol, about 2,500 g/mol or about 3,000 g/mol.
