CO-POLYESTER PACKAGING RESINS PREPARED WITHOUT SOLID-STATE POLYMERIZATION, A METHOD FOR PROCESSING THE CO-POLYESTER RESINS WITH REDUCED VISCOSITY CHANGE, AND CONTAINERS AND OTHER ARTICLES PREPARED BY THE PROCESS

摘要

A method of processing a polyester composition without changing the Intrinsic viscosity of the polyester polymer by more than 0.025 dL/g such as Injection molding a PET resin to form a bottle perform and blow molding a container from the bottle preform.
