The polyethylene terephthalate composition includes a polyester resin containing terephthalic acid, isophthalic acid, ethylene glycol and cyclohexane dimethanol and residual amount of catalytic composition comprising Sb and Ti. The polyethylene terephthalate composition is especially useful for large blow moldings and provides a change in the fill point volume after 5 wash cycles of a 2.5 liter blow molded bottle of 14 ml or less.

Abstract: A drum heater assembly includes an inner body defining a cylindrical interior space shaped to receive a drum containing a material in the drum, and an elongated heating panels coupled to exterior surfaces of the inner body. The heating panels include heating elements configured to generate heat toward the interior space. The drum heater assembly also includes outer doors coupled with the heating panels such that the heating panels are disposed between the outer doors and the inner body. The inner body is configured to open to remove the drum and insert another drum into the interior space for heating by the heating panels.

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.
