Abstract

This invention relates to polyester materials such as polyethylene terephthalate (PET) and products such as bottles, containers, films and sheets made therefrom. The invention includes the use of certain 'enaminones' including a preferred class of heterocyclic compounds which are present during melt processing of such polyester materials in order to reduce the content of actealdehyde (AA).
