  • Reactive block copolymers for the preparation of inorganic tubule-polymer composites
    Patent number: 8557907
    Abstract: A method for modifying an inorganic tubule, such as halloysite, cylindrite, boulangerite, or imogolite, with a functionalized block copolymer for improving compatibility with a thermoplastic or thermoset polymer matrix and a composition for the modified inorganic tubule and for the modified inorganic tubule-polymer matrix are provided. In one embodiment, the block copolymer can be added to a slurry of the inorganic tubules. The pH of the slurry can be manipulated to promote ionic bonding between the inorganic tubules and one block of the block copolymer. The other block of the block copolymer is selected for compatibility with the polymer matrix for a particular application.

  • Decorated wheel with a permanent stylized cover and process for its manufacture
    Publication number: 20060261665
    Abstract: A decorated wheel is depicted having a permanent stylized cover comprising: a base wheel; an intermediate coat made from a low-density polymer attached on the outer face of the base wheel; and a stylized cover permanently attached on the intermediate layer; the stylized cover has a shape, color, and brightness according to a previously established design, is made from a thermoformable polymer such as bisphenol A polycarbonate o the copolymers thereof, or is made from stainless steel; if the stylized cover is made from bisphenol A polycarbonate or the copolymers thereof, it has a class “A” finish on its surface; also, a process to manufacture the decorated wheel with a stylized permanent cover is depicted and, in the process, the stylized cover and the base wheel form a closed chamber where the intermediate layer made from the low-density polymer is encapsulated.
