Polyester bottle resins having reduced frictional properties and methods for making the same

摘要

The invention is a polyester resin that includes between about 20 and 200 ppm of an inert particulate additive, preferably selected from the group consisting of surface-modified talc and surface-modified calcium carbonate. The invention is also a method of making the polyester resin, which is capable of being formed into low-haze, high-clarity bottles possessing reduced coefficient of friction.
