Abstract

This invention relates to certain linear, low-molecular-weight polyester-based polyols having at least two hydroxyl groups, low viscosity, high solids content and having the structural formula: ##STR1## wherein R is a moiety derived from a saturated aliphatic polyhydric alcohol; n is 1 or 2, and at least about 50% by weight, of n is n=1; p is 0 to 4 inclusive and m is 2 to 10 inclusive; said polyol being substantially free of any unreacted polyhydric alcohol.
