  • Composition for tufted carpets containing azidosulfonyl silane crosslinker
    Patent number: 4552794
    Abstract: Disclosed is a pre-coat composition consisting essentially of (1) a low density polyethylene having a melt index of from about 70 to about 425; (2) a nitrogen-containing silane cross-linking compound, (3) a resin having a Ring and Ball softening point from about 50.degree. C. to about 115.degree. C.; (4) a hydrocarbon wax; and (5) optionally naphthenic oil. The composition is useful in the manufacture of tufted carpets.

  • Hydrophobically modified polymers
    Patent number: 4529523
    Abstract: The amount of oil which can be recovered from an oil containing subterranean formation is increased by using a water flooding medium. The performance of a water flooding medium is improved where a nonionic, hydrophobically modified, water-soluble polymer, is used as a thickener.

  • Dihydroxypropyl mixed ether derivatives of cellulose
    Patent number: 4523010
    Abstract: Disclosed are nonionic dihydroxypropyl hydroxyalkylcelluloses having a dihydroxypropyl M.S. of from about 0.1 to 1.2 and a hydroxyalkyl M.S. of from about 1.5 to about 3.0. The dihydroxypropyl hydroxyalkylcelluloses are capable of reacting with polyvalent metal cations, such as, titanium and zirconium, in an aqueous medium, such as a salt brine medium, to form viscoelastic gels useful in oil recovery operations.

  • Carboxymethyl hydroxyethyl cellulose composition
    Patent number: 4486335
    Abstract: A water-soluble carboxymethyl hydroxyethyl cellulose having a carboxymethyl degree of substitution of about 0.1 to about 0.25, preferably of about 0.15 to about 0.20, and having a hydroxyethyl molar substitution of greater than about 1.0 possesses unexpected qualities. When this composition is crosslinked with a suitable aluminum ion in an aqueous solution it forms a gel which exhibits no significant thinning at temperatures less than about 200.degree. F.

  • Coaxial cables
    Patent number: 4440973
    Abstract: A dielectric system for coaxial electrical conductors is provided. The dielectric system separates an inner and outer conductor and is composed of a first layer of braided high tensile strength polymeric fluorocarbon filaments in an open weave surrounding the inner conductor. Surrounding the layer of braided filaments is a continuous layer of a polymeric film which is in turn surrounded by a continuous layer of a crosslinkable polymeric lacquer enclosing both the layer of braided filaments and the layer of polymeric film.

  • Stabilization of irradiated carboxymethyl cellulose
    Patent number: 4420611
    Abstract: The molecular weight of irradiated carboxymethyl cellulose can be stabilized by heat treatment of irradiated carboxymethyl cellulose at a temperature from about 50.degree. C. to about 150.degree. C., preferably from about 70.degree. C. to about 90.degree. C. Equal amounts of such stabilized carboxymethyl cellulose have essentially the same viscosity regardless of the time that has passed from irradiation until a solution is made.

  • Readily dispersible anionic, water-soluble cellulose derivatives and a method for their preparation
    Patent number: 4400502
    Abstract: Anionic, water-soluble cellulose ethers which are treated with a mixture of glyoxal and a sodium borate, preferably borax, readily disperse in aqueous solutions without clumping or agglomerating. These treated compounds can be formed by contacting an organic slurry of an anionic, water-soluble cellulose ether with an aqueous solution of glyoxal and a sodium borate, recovering the product and then drying it.
