Abstract
The present invention relates to a polyester polymer composition containing inorganic black particles in the range of about 5 to about 150 parts per million based on the polymer. The size of the inorganic black particles is greater than about 0.5 microns. Such polyester polymers having inorganic black particles incorporated therein absorb infrared radiation better than polymers containing no inorganic black particles and thus in the production of plastic bottles less energy is required to blow-mold the bottles.
