  • Patent number: 5539044
    Abstract: Flow of a stream comprised of hydrocarbons is improved by introducing into the stream a stable, non-agglomerating suspension comprising:(a) water,(b) highly dispersed in the water, and substantially insoluble therein, and extremely finely-divided, non-crystalline, ultra-high molecular weight, hydrocarbon-soluble, undegraded polyalkene having 2 to about 30 carbon atoms per alkene precursor and an inherent viscosity of at least 20 dL/g, and(c) a small but effective amount of a surfactant having a HLB of at least about 9. The finely divided polyalkene is prepared by polymerization and then cryogrinding below the glass transition temperature of the polyalkene.

  • Patent number: 5498649
    Abstract: Thermoplastic elastomeric ablative insulation having low density are disclosed. The ablative insulation is based upon a thermoplastic elastomeric polymer resin containing a polyamide polymer and a maleic anhydride modified EPDM polymer. The ratio of polyamide polymer to maleic anhydride modified EPDM is in the range from about 20:80 to about 40:60. Carefully selected fillers provide suitable charring and ablative insulation performance without unduly increasing the insulation density. Typical fillers include an phosphorus containing compound, such as ammonium polyphosphate, a polyhydric alcohol present, such as pentaerythritol, silicone resin, chopped fibers, an antioxidant, a butadiene polymer, and a peroxide.
