Abstract: The present disclosure relates to masterbatch compositions used for preparing articles, preforms or containers comprising a base polyester, a transition metal-based oxidation catalyst, an alkali metal compound, and an alkaline earth metal compound. The masterbatch compositions have desirable viscosity characteristics and the prepared articles, preforms or containers using these masterbatch compositions have desirable mechanical, visual and gas barrier properties.
