Solid-phase polymerization was manufactured without co - polyester packaging resins, copolymers and reduce the viscosity variation - processing method polyester resin, and the containers and other products produced 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.
