Abstract: The present invention relates to a polyester-platelet particle composite comprising at least one polyester having dispersed therein a platelet particle dispersion comprising chalcogen or platelet particles and at least one water dissipatible polymer.

Abstract: The present invention relates to new polyester compositions, novel processes to prepare molded articles from these new polyester compositions, and novel containers fabricated from polyester/clay composites for food and beverages. The processing methods employed in this invention enable containers to be formed which exhibit excellent clarity. Specifically, the present invention relates to a process comprising forming a parison from a composite composition comprising about 0.01 to about 25 weight % platelet particles dispersed in at least one polyester at a processing temperature which is at least 50° above the Tg of said polyester; and molding said parison into a clear, thin walled article.

Abstract: The present invention relates to an apparatus and method for producing molded polyester articles. More particularly, the invention concerns an apparatus and method for continuously producing molded polyester articles having low acetaldehyde content from a melt prepared by continuously reacting polyester precursors. The polyester is prepared and formed into useful shaped articles in a single, integrated, continuous melt-to-mold process without an intermediate solidification of the melt.
