A poly(neopentylpolyol) ester composition is produced by reacting a neopentylpolyol having the formula: wherein each R is independently selected from the group consisting of CH3, C2H5 and CH2OH and n is a number from 1 to 4, with at least one monocarboxylic acid having 2 to 15 carbon atoms in the presence of an acid catalyst and at an initial mole ratio of carboxyl groups to hydroxyl groups of greater than 0.5:1 to 0.95:1 to form a partially esterified poly(neopentylpolyol) composition. Then the partially esterified poly(neopentylpolyol) composition is reacted with additional monocarboxylic acid having 2 to 15 carbon atoms to form a final poly(neopentylpolyol) ester composition.
