  • Patent number: 6841592
    Abstract: Cationic mordants are described that will not significantly interact with anionic dyes in aqueous jet inks, but will form strong complexes with the dyes on the substrate as the water is absorbed and dissipated. The mordants are cationic amide salts of maleated hydrocarbons, and when in aqueous dispersions have an average particle size of less than one micron. These materials result in less feathering of the ink during printing and improved waterfastness of the ink on a paper substrate.

  • Patent number: 5767183
    Abstract: A heat shrinkable silicone tube is prepared from a silicon rubber composition comprising (A) a diorganopolysiloxane, (B) a thermoplastic resin, (C) finely divided silica, (D) an inorganic filler of titanium white, alumina, quartz powder or talc having a mean particle size of 0.5-15 .mu.m, and (E) a curing agent by extrusion molding the silicone rubber composition into a tubular shape preferably at a drawdown of 150-250%, vulcanizing the tube, and heat stretching the tube in a radial direction. The tube exhibits axial orientation during the stretching step and a shrinking step subsequent thereto and is thus tearable.

  • Patent number: 5721322
    Abstract: The specification discloses a method and additive for increasing the surface activity of non-polar polymeric materials, and a non-polar polymeric material exhibiting increased surface activity. The invention employs an additive of the formulaA-B-A.sup.1wherein each of the A and A.sup.1 blocks which may be the same or different has a number molecular weight in the range of from about 200 to about 1000 daltons and is selected from the group substituted and unsubstituted alkyl, cycloalkyl, alkenyl, cycloalkenyl, aryl and alkylaryl units derived from one or more esters, organic acids, organic halides or organic acid halides, and units derived from alkyl or aryl isocyanates or ester-amides. The B-block is a polyepichlorohydrin unit derived from a polyepichlorohydrin polyol having at least two terminal hydroxyl groups and having an average molecular weight in the range of from about 400 to about 4000 daltons.

  • Patent number: 5621032
    Abstract: A method and product which provides a solid, non-powdered homogeneous form to liquid and low melting point solid compounds which facilitates stability, storage, dispersability and handling and which may be added directly to formulations requiring the liquid compound or low melting point solid compound. The liquid or low melting point solid ingredient is combined with a binder which is comprised of at least a wax and thermoplastic polymer. During the method of forming the product, both the binder and the liquid compound (or low melting point solid compound) pass through a liquid phase during which they are mixed. The product is then formed and cooled.

  • Patent number: H1955
    Abstract: Films, made of polyethylenes and fillers, and articles made therefrom greater WVTR than previously available films based on conventional Ziegler-Natta based polyethylenes. The polyethylenes are produced in a metallocene-catalyzed production process. The films may be made by a cast film process, and may be made in widely varying filler content, generally polyethylene to filler ratios of 30/70 to 70/30. The metallocene based polyethylenes when combined with filler also permit the extrusion of thinner films leading to lighter weight and softer films. The m-polyethylenes utilized for making such films typically have a Composition Distribution Breadth Index above 50%, a Mw/Mn below 3, and a Mz/Mw below 2.

  • Patent number: H1798
    Abstract: A soft multicomponent compound comprising a styrenic block copolymer having good elastomeric properties, a paraffinic oil, a crystalline polyolefin and a metallocene polyolefin having a density from 0.86 to 0.91, a molecular weight distribution less than 3, and good distribution of ethylene and from 12% to 30% by weight of one or more .alpha.-olefin monomers having from 4 to 12 carbon atoms. The metallocene polyolefin partly replaces the styrenic block copolymer in conventional soft compounds and provides the desired softness at significantly lower oil contents, thus avoiding surface tackiness and oil extractability.
