Abstract

Embodiments of the invention provide for a polycarbonate polyol including the reaction product of at least one polyol composition and a carbonate. The polycarbonate is one of an amorphous liquid and an amorphous solid at room temperature. The polyol composition includes at least one of a mixture of 1,3-cyclohexanedimethanol and 1,4-cyclohexanedimethanol in a weight ratio from about 60:40 to about 5:95 and a polyol derived from a natural oil fatty acid or natural oil fatty acid methyl ester.
