    摘要： There is disclosed a process for reducing the number of gels generated in polyethylene terephthalate (PET) resin. Gels are crosslinked polymers created by thermal and thermo-oxidative degradation induced during polymer production. The instant process comprises the addition of primary and secondary antioxidants prior to the PET polycondensation reaction in order to reduce the amount of thermal degradation which occurs. The polyethylene terephthalate produced by this process formed approximately 25 to 90% fewer gels while maintaining physical properties suitable for use in fiber, film, and molding applications.

    摘要： Volatile organic compound or other materials are produced in the thermoplastic manufacture of thermoplastic polyester beverage containers. Such materials can be eluted into beverages such as carbonated beverages, sparkling or still water from the polyester. Such thermoplastic polyester resins can be manufactured with a substituted cyclodextrin material that can prevent the formation of, or react with, and absorb volatile by-products during the formation of thermoplastic preforms or containers from the thermoplastic pellet or chip. Further, as the preform is blown into a polyester container, the active materials of the invention prevent the generation of additional undesirable volatile materials. Lastly, the scavenger material can act as a barrier that prevents transport of materials from the exterior of the container into the container contents.
