Abstract
A method of polymerizing at least one .beta.-substituted-.beta.-propiolactone in the presence of a catalytic amount of isobutylaluminoxane in a solvent for the .beta.-propiolactone(s) and isobutylaluminoxane for a time and at a temperature to produce a poly(.beta.-substituted-.beta.-propiolactone) polyester and the polyesters produced thereby are disclosed.
