  • Injection moldable poly(ethylene terephthalate)
    Patent number: 4390649
    Abstract: A molding composition of a terephthalate polyester such as PET, a plasticizing material and a crystal nucleating agent. The nucleating agent is a powdered metal hydroxide such as aluminum hydroxide, which raises the T.sub.cc of the composition and permits reduced cycling time and enables higher molecular weight polymer to be used in the molding process.
