Abstract
Cyclic esters are polymerized in the presence of a catalytic amount of a Group 4 transition metal hydride. The method is capable of producing high molecular weight polyesters with low polydispersities. These high molecular weight polyesters exhibit improved mechanical properties and are useful in a variety of product applications.
