  • Patent number: 6162851
    Abstract: A highly flame retardant, impact modified polyolefin alloy is described, the composition of which includes: at least one polyolefin; at least one halogenated organic flame retardant; at least one semi-crystalline ethylene copolymer impact modifier, the copolymer optionally being functionalized, at least one oxygen-containing metal compound wherein the metal is selected from the group consisting of Group III, IV, V, and VI of the Periodic Table; and at least one fluorocarbon, at least a portion of which is fibrillated or fibrillatable. Optionally, the alloy will contain at least one of a functionalized silicone polymer, a hydrated metal silicate, a hydrated metal borate, a primary antioxidant, and a secondary antioxidant. Such thermoplastic polymer blends/alloys can be produced by combining all ingredients in a melt and applying shear to the melt through means of a high shear internal/continuous mixer or an extruder.

    Inventors: David W. Smith, Steven D. Landau
  • Patent number: 5037787
    Abstract: The present disclosure is directed to a nickel pillared interlayered clay characterized by a temperature program reductin maxima of less than 500.degree. C., a Type V adsorption/desorption isotherm and a bimodal pore size distribution. This clay has particular application in the catalytic hydrogenation of an unsaturated edible oil wherein an edible oil is contacted with catalytically effective amount of the clay.

  • Patent number: 4963518
    Abstract: The instant disclosure is directed to a silanated metal-pillared interlayered clay which comprises the reaction product of a metal-pillared interlayered clay and a silanating agent. The clay finds application as a catalyst in the isomerization of olefins and in the conversion of syngas intermediates into hydrocarbon streams rich in C.sub.3 and C.sub.4 hydrocarbons.

  • Patent number: 4665045
    Abstract: A process for preparing a pillared layered lattice clay, comprising the steps of preparing a hydrolyzed solution of chromium ion by reacting a solution of a salt of the said metal with a base at temperatures above 60.degree. C., aging the solution at or above the said temperatures to develop the hydrolyzed pillaring agent, and contacting an aqueous slurry of a smectite, vermiculite, or flurohectorite with the hydrolyzed solution, and recovering the intercalated pillared clay product. The resultant products have unit cells containing from 1.2 to 4.2 chromium ions per cell, and have a repeating spacing of from about 18 to 28 Angstroms. The products are uniquely active catalysts for numerous applications, e.g., in the petrochemical industry.
