Abstract
The invention embraces polyester resins and containers that include surface-modified talc. The invention also embraces a method for the late introduction of surface-modified talc via a reactive carrier to achieve a polyester resin that is capable of being formed into low-haze, high-clarity bottles possessing reduced coefficient of friction.
