Abstract
Low unsaturation, high molecular weight polyols having an unsaturation level below or equal to 0.006 milli-equivalents per gram, and preferably below 0.004 milli-equivalents per gram, and molecular weights of greater than or equal to about 2,000, and preferably between about 2,000 and 10,000, are converted into low unsaturation, high molecular-weight (LUSHMW) polyamines directly by amination reactions. The LUSHMW polyamines produce polymers having elongation, modulus, and tensile characteristics that are substantially better than those of conventional analogous polymers.
