Abstract
Compositions of thermoplastic polyesters containing dispersed nanoparticles of fibrous clay are made by polymerizing the polyester precursors in the presence of exfoliated fibrous clay that has not been organically modified. The compositions have good physical properties and can be melt molded into various articles. Many of these articles may be coated (painted) and are especially useful for appearance parts such as visible exterior automotive body parts.
