Patent number: 7193015Abstract: A method of using nanostructured chemicals as alloying agents for the reinforcement of flouropolymer microstructures, including polymer coils, domains, chains, and segments, at the molecular level. Because of their tailorable compatibility with fluorinated polymers, nanostructured chemicals can be readily and selectively incorporated into polymers by direct blending processes. Properties most favorably improved are time dependent mechanical and thermal properties such as heat distortion, creep, compression set, shrinkage, modulus, hardness and abrasion resistance. In addition to mechanical properties, other physical properties are favorably improved, including lower thermal conductivity, fire resistance, and improved oxygen permeability. These improved properties may be useful in a number of applications, including space-survivable materials and creep resistant seals and gaskets. Improved surface properties may be useful for applications such as anti-icing or non-wetting surfaces or as low friction surfaces.Type: GrantFiled: March 31, 2004Date of Patent: March 20, 2007Inventors: Joseph M. Mabry, Rene I. Gonzalez, Rusty L. Blanski, Patrick N. Ruth, Brent D. Viers, Joseph J. Schwab, Joseph D. Lichtenhan

Patent number: 7176269Abstract: The curable composition of the present invention contains (A1) a silyl-containing ethylene/?-olefin/non-conjugated polyene random copolymer rubber which has a structural unit derived from a norbornene compound as the non-conjugated polyene with at least one specific vinyl group at the terminal and contains a specific hydrolyzable silyl group, and (B) a compound, other than the rubber (A1), having a hydroxyl group and/or a hydrolyzable group, e.g., (B1) a compound having a silanol group and/or a compound which can react with moisture to form a compound having a silanol group in the molecule. This compound improves elongation of the cured product and residual surface tackiness, and, at the same time, is high in curing speed and capable of giving the cured product of high resistance to weather. It is suitable for, e.g., adhesives, tackifiers, paints, sealants, waterproof materials, spray materials, shaping materials and casting rubber materials.Type: GrantFiled: July 24, 2001Date of Patent: February 13, 2007Assignee: Mitsui Chemicals, Inc.Inventors: Takashi Hakuta, Masaaki Kawasaki, Yoshiharu Kikuchi, Mitsunao Arino, Mitsuko Nagai, Hiroaki Sakaguchi, Masaki Sugawara, Masao Kishi, Kaoru Ueno, Takashi Abe, Michio Sekine
