  • Patent number: 8785507
    Abstract: This invention relates to viscoelastic silicone rubber compositions that are the products of the reaction of: (a) a silanol-terminated polyorganosiloxane base; (b) a boron-containing crosslinking agent; and (c) a siloxane bond-forming crosslinking agent. In a viscoelastic silicone rubber composition of the invention some of the crosslinks, the siloxane crosslinks, are permanent and others of the crosslinks, the boron-containing crosslinks, are temporary. Because a fraction of its crosslinks can come apart and then reform, a viscoelastic silicone rubber composition of the invention can relax stress in response to strain and thus adapt to new shapes. The composition has sufficient permanent crosslinks, however, to establish a permanent equilibrium shape to which the composition will eventually return when not subject to any imposed stress.

  • Publication number: 20130210621
    Abstract: A breathable film formed from a thermoplastic composition that contains a rigid renewable polyester and has a voided structure is provided. To achieve such a structure, a thermoplastic composition that contains a renewable polyester and polymeric toughening additive is extruded onto a surface to form a precursor film in which the toughening additive can be dispersed as discrete physical domains within a continuous matrix of the renewable polyester. The precursor film is thereafter stretched or drawn at a temperature below the glass transition temperature of the polyester (i.e., “cold drawn”). Without intending to be limited by theory, the present inventors believe that the deformation force and elongational strain of the drawing process causes debonding to occur in the renewable polyester matrix at those areas located adjacent to the discrete domains. This creates a network of voids located adjacent to the discrete domains.

  • Publication number: 20120288727
    Abstract: Subject is rocket foam. This letters patent is for construction of a space craft from acrylonitrile foam polymer. The new art involves making a polymer sheet plasticized with sulfur dioxide gas. The plasticize sheet is drape formed and then heated to drive off the gas leaving a rigid foamed polymer shape. The sheet during plasticize step is given a thin adherent layer of sand mingled in acrylonitrile polymer powder. Thermal heating during rocket reentry orbit generates a skin layer of carbide. The carbide protects against flame temperature air, to prevent combustion of the underlying carbon foam structure. A variation is to make the acrylonitrile polymer as a latex paint and apply such paint to a screen form geometry.

  • Publication number: 20090234036
    Abstract: To provide a method for producing a rigid polyurethane foam, whereby it is possible to reduce the density without causing deterioration in dimensional stability, and a rigid polyurethane foam. A method for producing a rigid polyurethane foam, which comprises a step of reacting a polyol having a hydroxyl value of from 200 to 800 mgKOH/g with a polyisocyanate compound in the presence of an amino-modified silicone, a catalyst, a blowing agent and a surfactant.

  • Patent number: 7030168
    Abstract: Supercritical fluid-assisted deposition of materials on substrates, such as semiconductor substrates for integrated circuit device manufacture. The deposition is effected using a supercritical fluid-based composition containing the precursor(s) of the material to be deposited on the substrate surface. Such approach permits use of precursors that otherwise would be wholly unsuitable for deposition applications, as lacking requisite volatility and transport characteristics for vapor phase deposition processes.

  • Patent number: 6632850
    Abstract: Microporous materials and articles are disclosed. The microporous materials contain a crystallizable propylene-containing polymer, a beta-nucleating agent, and a diluent that is miscible with the polymer at a temperature above the melting temperature of the polymer and that phase separates from the polymer at a temperature below the polymer crystallization temperature. The invention is also directed to methods of forming the microporous material using thermal induced phase separation and subsequent processing.
