Patent number: 6391953Abstract: The invention relates to a coating compound for fibers and to a process for the production thereof The invention relates in particular to a preparation agent for elastanes, based on a dispersion of fatty-acid metal salts and an agglomeration inhibitor in polyorganosiloxanes and mineral oils. The preparations are produced by a precipitation process from which fined-particle and sedimentation-stable dispersions with a narrow particle size distribution are obtained which are free from agglomerates.Type: GrantFiled: February 5, 1999Date of Patent: May 21, 2002Assignees: Bayer Aktiengesellschaft, Bayer Faser GmbHInventors: Stephan Hütte, Bernd Klinksiek, Andreas Endesfelder, Hans-Joachim Wollweber, Hans-Josef Behrens

Patent number: 6335384Abstract: Disclosed are methods useful for treating vascular lesions wherein a non-particulate agent such as a metal coil is introduced into a vascular site (e.g., an aneurysm cavity) in conjunction with an embolizing composition comprising a biocompatible polymer and a biocompatible solvent. The biocompatible solvent is miscible or soluble in blood and also solubilizes the polymer during delivery. The biocompatible polymer is selected to be soluble in the biocompatible solvent but insoluble in blood. Upon contact with the blood, the biocompatible solvent dissipates from the embolic composition whereupon the biocompatible polymer precipitates. Precipitation of the polymer in the presence of the non-particular agent permits the agent to act as a structural lattice for the growing polymer precipitate. In another embodiment, the biocompatible polymer composition can be replaced with a biocompatible prepolymer composition containing a biocompatible prepolymer.Type: GrantFiled: October 10, 2000Date of Patent: January 1, 2002Assignee: Micro Therapeutics, Inc.Inventors: Scott Evans, John Perl, II, Richard Greff

Patent number: 6329452Abstract: This invention relates to polyurethane compositions, and relates in particular to elastic polyurethane fibres resulting therefrom, which contain a dialkyl sulphosuccinate as an additive and/or which are finished with a polydialkylsiloxane, with a dialkyl sulphosuccinate and optionally with a mineral oil. As a result of this addition or of the preparation of the polyurethane composition or of the elastic polyurethane fibres with dialkyl sulphosuccinate, electrostatic charging of the polymer, such as that which occurs during the processing of warp-knitted fabric made of polyurethane fibres for example, is suppressed.Type: GrantFiled: February 5, 1999Date of Patent: December 11, 2001Assignee: Bayer AktiengesellschaftInventor: Stephan Hütte

Patent number: 6103798Abstract: Thermoplastic compositions are provided containing a saturated hydrocarbon amine oxide and stabilizer compositions are provided containing a saturated hydrocarbon amine oxide and a second stabilizer. The thermoplastic compositions exhibit good melt flow rate stability during processing and are useful for making molded and extruded articles. The stabilizer compositions are useful for addition to thermoplastics for the stabilization thereof. A method is also provided for stabilizing thermoplastic compositions and involves admixing a hydrocarbon amine oxide with a thermoplastic resin. The saturated hydrocarbon amine oxides are preferably trialkyl amine oxides. The thermoplastic resin is preferably a polyolefin resin.Type: GrantFiled: May 26, 1998Date of Patent: August 15, 2000Assignee: General Electric CompanyInventors: Vaikunth S. Prabhu, Roger W. Avakian
