The incorporation of the non-silicone hydrophobic polymer increases the durability of the coating on the device without sacrificing lubricity.Type: GrantFiled: October 3, 2003Date of Patent: May 9, 2006Assignee: Ethicon, Inc.Inventors: Jesse G. Nawrocki, Dennis D. Jamiolkowski

Patent number: 7022801Abstract: A fluorine containing polymer which acts as a wetting, flow or leveling agent, and has at least one polar group. The polymer has at least one pendant or ether side chain containing from about 1 to about 20 carbon atoms with at least 25% of the hydrogen atoms being replaced by fluorine atoms. The fluorinated polymers unexpectedly impart wetting, flow or leveling properties to a variety of coatings while producing little foam.Type: GrantFiled: September 5, 2003Date of Patent: April 4, 2006Assignee: Omnova Solutions Inc.Inventor: Robert E. Medsker

Patent number: 6933345Abstract: The nanoscopic dimensions of polyhedral oligomeric silsesquioxanes (POSS) and polyhedral oligomeric silicates (POS) materials ranges from 0.7 nm to 5.0 nm and enables the thermomechanical and physical properties of polymeric materials to be improved by providing nanoscopic reinforcement of polymer chains at a length scale that is not possible by physically smaller aromatic chemical systems or larger fillers and fibers. A simple and cost effective method for incorporating POSS/POS nanoreinforcements onto polymers via the reactive grafting of suitably functionalized POSS/POS entities with polymeric systems amenable to such processes is described. The method teaches that the resulting POSS-grafted-polymers are particularly well suited for alloying agents by nongrafted POSS entitles such as molecular silicas. The successful alloying of POSS-polymers is aided because their interfacial tensions are reduced relative to non-POSS containing systems.Type: GrantFiled: January 23, 2003Date of Patent: August 23, 2005Assignee: Hybrid Plastics, LLPInventors: Joseph D.

Patent number: 6906147Abstract: This invention relates to single-component and multi-component catalytic systems using aryl titanates. Aryl titanate compounds are useful as catalysts and co-catalysts in single-component and multi-component catalytic systems (e.g., for the polymerization of macrocyclic oligoesters and the depolymerization of polyesters). Multi-component catalytic systems using aryl titanates allow increased versatility in applications such as liquid molding.Type: GrantFiled: March 20, 2002Date of Patent: June 14, 2005Assignee: Cyclics CorporationInventors: Yi-Feng Wang, Peter D.

Patent number: 6905774Abstract: Biaxially-drawn polyester film for fabrication which is characterized in that it is a film comprising polyester in which ethylene terephthalate units and/or ethylene naphthalate units are the chief structural component, and the melting point of said film is 180-270° C., the angle of contact to water is 70°-120°, and the planar orientation coefficient is 0.08-0.15. This film shows outstanding release properties following repeated use, use after fabrication and use in an aqueous environment and, furthermore, it exhibits stable properties with little variation and, in particular, following lamination to metal sheet such as steel or aluminium, when used as the inner face of a fabricated metal can, it is outstanding in its non-stick properties to the contents, and provides a combination of heat resistance and processability.Type: GrantFiled: August 27, 2003Date of Patent: June 14, 2005Assignee: Toray Industries, Inc.Inventors: Kohzo Takahashi, Ryosuke Matsui, Masahiro Kimura
