Abstract
The present invention relates to slow-crystallizing, titanium-catalyzed polyethylene terephthalate resins that are useful for making high-strength, high-clarity bottles that possess improved resistance to stress cracking and thermal creep. The polyethylene terephthalate resins possess improved reheating profiles and are especially useful for making polyester articles that have exceptional clarity, dimensional stability, and thermal stability.
