Abstract
Polyesters are formed from diols and dibasic carboxylic acids at an OH/COOH ratio to provide --OH termination, and then end-capped with tribasic carboxylic acids. A major portion of the dibasic carboxylic acids used to form the polyesters have the formula: ##STR1## where x=8-32, y=0-8, x+y=8-32. The polyesters are used as support resins for forming acrylic resin emulsions. The polyester/acrylic acid emulsions are useful, for example, as textile size.
