Vinyl ether terminated ester oligomers having a range of molecular weights are prepared by reacting a vinyl ether terminated polybasic ester with a polyol in the presence of a catalyst. Continual removal of a hydroxy monovinyl ether avoids formation compounds containing acetal moieties. Alternatively, a polybasic ester is chain extended with a polyol with continual removal of the alcohol by-product. Then, the terminal ester moieties are end capped with a monohydroxy vinyl ether. The oligomers have application in coatings and the like.
