High clarity, low haze polyesters having reduced infrared heat-up times

摘要

This invention discloses a high clarity, low haze polyester having improved heat-up rates which contains a very small amount of an infrared absorbent material, such as carbon black. This polyester is very useful as a material for making preforms for trays, containers, and the like. It is especially useful as a material from which beverage bottles can be made.
