Abstract
Disclosed are polyol compositions with a low viscosity that exhibit superior heat resistance, enhanced stability in the presence of water, improved strength, hardness, and molding characteristics relative to known polyurethane materials. Disclosed is a polyol composition comprising: (a) at least one monomeric polyol comprising three or more hydroxyl groups; (b) at least one higher polyol comprising three or more hydroxyl groups; and (c) at least one polyhydroxylated aromatic compound; wherein the at least one higher polyol comprises residues of either or both of the at least one monomeric polyol and the polyhydroxylated aromatic compound linked by one or more carbonate groups, oxygen ether groups, or a combination thereof. Disclosed are methods of preparing the disclosed compositions. Disclosed are articles prepared from the disclosed compositions that exhibit flexural strengths in excess of 10,000 psi and flexural moduli in excess of 400,000 psi, and exhibit outstanding green strength.
