Abstract
A process for the preparation of new polyols and polyesters from a natural oil or other unsaturated fatty acid esters is described. The process involves ozone cleavage of double bonds in the fatty acid chains of the oils along with coupling of a hydroxylated compound such as a mono-alcohol, a diol, or a polyol to the cleaved ends of the molecules resulting from the cleavage with a base. The resulting polyols and polyesters are as intermediates for polymers.
