Patent number: 5594046Abstract: The invention relates to an intumescent one-component sealant based on polyurethane and containing an intumescent agent and a vitreous fusible filler. The intumescent agent and the vitreous filler have been pretreated by reaction with an isocyanate having a functionality of at least 2. The sealant is stable in storage and is an effective fire barrier in the event of fire.Type: GrantFiled: May 30, 1995Date of Patent: January 14, 1997Assignee: Bostik, Inc.Inventor: Roland Joachimi

Patent number: 5539044Abstract: 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.Type: GrantFiled: September 2, 1994Date of Patent: July 23, 1996Assignee: Conoco In.Inventors: Aysen Dindi, Ray L. Johnston, Yung N. Lee, Debora F. Massouda

Patent number: 5521234Abstract: A Fluidized Polymer Suspension (FPS) thickener comprising a hydroxyethylcellulose and/or alkyl or arylalkyl hydrophobically modified hydroxyethylcellulose added continuously to an aqueous dispersion increases productivity for manufacture of aqueous coating compositions. The FPS can be stored and metered without delays associated with dry powders. A latex paint is continuously produced by simultaneously or sequentially mixing latex binder, dispersed pigment and FPS thickener along with other ingredients.Type: GrantFiled: April 29, 1994Date of Patent: May 28, 1996Assignee: Aqualon CompanyInventors: Richard G. Brown, Charles L. Burdick, Charles W. Vanderslice

Patent number: 5498649Abstract: 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.Type: GrantFiled: May 18, 1993Date of Patent: March 12, 1996Assignee: Thiokol CorporationInventor: David G. Guillot
