  • Process for preparing an exfoliated, high I.V. polymer nanocomposite with an oligomer resin precursor and an article produced therefrom
    Publication number: 20020165306
    Abstract: This invention is directed to a process for preparing an exfoliated, high I.V. polymer-platelet particle nanocomposite comprising the steps of: (i) melt mixing platelet particles with a matrix polymer-compatible oligomeric resin to form an oligomeric resin-platelet with a high molecular weight matric polymer, thereby increasing the molecular weight of the oligomeric resin-platelet particle composite and producting an exfoliated, high I.V. polymer nanocomposite material. The invention also is directed to a nanocomposite material producted by the process, producted produced from the nanocomposite material, and a nanocomposite prepared from an oligomeric resin-platelet particle precursor composite.

  • Polyester-polyamide blends with reduced gas permeability and low haze
    Patent number: 6444283
    Abstract: The invention relates to polyester/polyamide blend compositions for forming an article having low haze and reduced gas permeability compared to the polyester alone. More specifically, the invention relates to blends of semi-crystalline polyesters such as PET with low molecular weight polyamides and to the containers and packages for food, beverages, cosmetics, pharmaceuticals and personal care products that can be fabricated from these blends.

  • High barrier amorphous polyamide-clay nanocomposite and a process for preparing same
    Patent number: 6417262
    Abstract: This invention is directed to a polyamide-clay nanocomposite, products produced from the nanocomposite, and a process for preparing a polyamide-clay nanocomposite. The polyamide-clay nanocomposite comprises (a) an amorphous matrix polyamide comprising (i) a residue of a dicarboxylic acid component comprising at least two diacids and (ii) a residue of a diamine component, and (b) a layered clay material, wherein the layered clay material is dispersed in the matrix polyamide.
