Packaging resins prepared without co polyester solid state polymerization, a method for processing 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.
