Abstract
The present invention relates to titanium-catalyzed polyethylene terephthalate resins that are capable of being formed into articles (e.g., carbonated soft drink and water bottle preforms) at reduced injection-molding cycle times. In particular, the titanium-catalyzed polyethylene terephthalate resins of the present invention can be formed into carbonated soft drink bottle preforms at reduced injection-molding cycle times to yield high-clarity, carbonated soft drink bottles that possess satisfactory resistance to stress cracking and thermal creep.
