Improved polyester-ether resin blends

The application relates to composition for preparing articles, preforms or containers comprising a base polyester; a copolyester-ether, and a transition metal-based oxidation catalyst; wherein delamination is reduced by reducing the melting point difference, determined according to ASTM D 3418-97, b...
