Abstract: The disclosure relates to processes for producing lightweight polyethylene terephthalate articles such as bottles that retain good batTier properties against the permeation of oxygen, carbon dioxide and/or water vapor. The use of relatively small amounts of polytrimethylene furandicm·boxylate during the formation of the PET bottles can produce a bottle having the required barrier properties and result in the use of less material.
