ABSTRACT:
There are disclosed herein polyester polyols, resinous polyols thereof, and coating compositions formulated therewith. The polyester polyols are prepared by typically reacting a large excess of low molecular weight polyols with polycarboxylic acid or functional equivalents thereof. The polyols are employed in amounts sufficient to produce reaction products containing a significant amount of unreacted polyols which can be subsequently removed by means such as vacuum distillation.
