  • Patent number: 6583208
    Abstract: Polyester resin compositions each comprising a polyester resin and a silane-treated phyllosilicate, wherein the silane-treated foliated phyllosilicate is one prepared by incorporating a swellable phyllosilicate salt with organo-silane of the general formula (I): YnSiX4−n (wherein n is an integer of 0 to 3; Y is an optionally substituted C1-C25 hydrocarbon group; and X is a hydrolyzable group or hydroxyl, with the proviso that when n or 4−n is 2 or above, nY's or (4−n)X's may be the same or different from each other) and the maximum layer thickness of the silane-treated foliated phyllosilicate in the composition is larger than 100 Å but smaller than 2000 Å.

  • Patent number: 6262162
    Abstract: Intercalated layered materials prepared by co-intercalation of a multi-charged onium ion spacing/coupling agent and a matrix polymer between the planar layers of a swellable layered material, such as a phyllosilicate, preferably a smectite clay. The spacing of adjacent layers of the layered materials is expanded at least about 3 Å, preferably at least about 5 Å, usually to about 15-20 Å, e.g., 18 Å with the di-charged onium ion spacing/coupling agent. The intercalation of the matrix polymer then increases the spacing between adjacent layers to at least about 15 Å, preferably to about 20 Å to about 30 Å.

  • Patent number: 6228922
    Abstract: A method is provided for forming a highly conductive metal-containing polymer fiber or sheet in which a polymer is immersed in a solution containing a metal precursor selected from organic or inorganic salts of copper, silver, aluminum, gold, iron and nickel. The metal precursor is then reduced by chemical, electrochemical, or thermal means such that conductive metal is incorporated into the polymer.
