  • Patent number: 9040598
    Abstract: A thermoplastic composition that contains a rigid renewable polyester and has a voided structure and low density is provided. To achieve such a structure, the renewable polyester is blended with a polymeric toughening additive to form a precursor material in which the toughening additive can be dispersed as discrete physical domains within a continuous matrix of the renewable polyester. The precursor material is thereafter stretched or drawn at a temperature below the glass transition temperature of the polyester (i.e., “cold drawn”). This creates a network of voids located adjacent to the discrete domains, which as a result of their proximal location, can form a bridge between the boundaries of the voids and act as internal structural “hinges” that help stabilize the network and increase its ability to dissipate energy. The present inventors have also discovered that the voids can be distributed in a substantially homogeneous fashion throughout the composition.

  • Patent number: 8501828
    Abstract: The present invention provides processes for producing re-bonded polyurethane foam constructs that are useful in applications such as carpet underlayments. According to the invention, a tertiary amine is employed as a catalyst either alone, or preferably in combination with other catalysts in a binder which comprises an organic isocyanate and a polyol. Inclusion of a tertiary amine as a catalyst dramatically increases production throughput.

  • Patent number: 8324285
    Abstract: Provided are methods of treating an open cell polyimide foam product to produce a treated polyimide foam product having a property of repelling water or oil. The method includes the steps of: selecting a polyimide foam product having an external surface area and an open cell structure that has an interior surface area, wetting the exterior surface area and the interior surface area with a chemical treatment fluid comprising a treatment chemical that has a property of repelling water or oil, and distributing the treatment chemical onto at least a portion of the interior surface area sufficient to modify a surface property of the interior surface. Also provided are treated polyimide foam products that have an open cell polyimide foam substrate with an interior surface area and a treatment chemical on at least a portion of the interior surface area. The treatment chemical renders the interior surface hydrophobic or oleophobic.

  • Publication number: 20120237606
    Abstract: A particulate body having a hollow particle and a surface polymer disposed on the outside of the hollow particle and suitable for use in solid phase synthesis, especially production of peptides and oligonucleotides. The particulate body may be used as a chromatography stationary phase column and the buoyancy of the body allows the column to be packed efficiently from the bottom reducing the risk of damage to the stationary phase. The buoyancy of the particulate body may also allow species for example a catalyst to be suspended in a liquid phase to allow reactions, for example hydrolysis of vegetable oil and esterification to produce biodiesel to be carried out with a reduced risk of catalyst loss from a reaction zone.
