Processes for producing very low iv polyester resin

The present invention provides processes for producing certain very low inherent viscosity polyesters. Also provided are the low inherent viscosity polyesters in discrete particulate form, and processes for producing the particulate polyesters. The discrete particulate materials are desirable for us...
