The polymer particles do not show instantaneous swelling, when contacted with water or a water-containing liquid, but show delayed water absorption after an appropriate period of time. The coated polymer particles may be used in oil fields, in mining, for construction chemical compositions or as carrier for active substances. The coated polymer particles are prepared by a suspension coating process or a fluidized bed coating process.Type: GrantFiled: April 5, 2017Date of Patent: May 25, 2021Inventors: Peter Leidinger, Piotr Antoni Bazula, Holger Misslitz, Gregor Herth, Stefan Friedrich, Maik Schlesinger

Patent number: 10883021Abstract: An adhesive article for masking a portion of a substrate surface from a liquid coating applied to the surface includes a support having first and second opposed major surfaces, and a cationic or zwitterionic adhesive composition disposed on at least a portion of at least one of the first and second opposed major surfaces. The adhesive composition provides a barrier that impedes the migration of the coating past the edge of the adhesive article.Type: GrantFiled: November 3, 2017Date of Patent: January 5, 2021Assignee: 3M Innovative Properties CompanyInventors: Mahfuza B. Ali, Elizabeth E. Johnson, Michael D. Crandall

Patent number: 10858532Abstract: A latex emulsion may include an aqueous carrier liquid and a latex copolymer formed from reactants comprising butyl methacrylate, wherein the reactants include at least 20 wt. % butyl methacrylate, based on the total weight of ethylenically unsaturated monomers used to make the latex copolymer. A coating formed from the latex emulsion exhibits a wet adhesion to a thermoplastic polyolefin roofing membrane of greater than about 1 pound per linear inch when tested using fabric embedded peel adhesion testing per ASTM C794. The latex emulsion may be used as part of an aqueous coating composition or a roofing system including a polymeric roofing membrane.Type: GrantFiled: April 12, 2019Date of Patent: December 8, 2020Assignee: SWIMC LLCInventors: Mary Jane Hibben, Allen Bulick, Brent Crenshaw, Ashley Rodgers, Glenn Frazee, Robert Sandoval

Patent number: 10844545Abstract: A method for wet production of a superabsorbent material. The method comprises forming an aqueous saline solution with a concentration of 0.01-4.5 N of ionic salt and a pH from 0 to 6.0 or from 8.0 to 14.0 by the addition of a strong acid or strong base; dispersing in the saline solution a water superabsorbent polymer (SAP); creating a first web by stratification and deposition under vacuum suction onto a mesh screen belt deposition section of the SAP dispersion; washing the web with a basic solution (or with an acidic solution) up to the desired level of neutralization of the acidity (or basicity) for SAP dispersions in acidic (or basic) saline solutions; washing the web with water and suction; and drying the web. The relationship between pH and salt concentration causes a water absorption in the SAP equal to or less than about 30.00 gH2O/gSAP.Type: GrantFiled: January 20, 2016Date of Patent: November 24, 2020Inventor: Gianfranco Palumbo

Patent number: 10793963Abstract: Provided in one example is a sensor having at least one fissure, the fissure being at least partially filled by at least one polymer formation extending vertically within a passivation layer. The polymer formation protects the underlying metal containing layer from corrosive solutions. Provided in another example is a method of forming the polymer formation in a fissure of a sensor.Type: GrantFiled: December 11, 2018Date of Patent: October 6, 2020Assignee: ILLUMINA, INC.Inventor: Hayden Black

Patent number: 10772821Abstract: An oral composition is described. The oral composition can include a solvent having water and a cosolvent chosen from lower alkyl alcohols and acetone; a basic copolymer having basic acrylate monomeric units, basic methacrylate monomeric units, or a combination thereof; no less than 0.5 wt-% of an acid buffering or neutralizing agent; and optionally an active agent. The oral composition can include from about 6° to about 15° wt % of water, from about 30° to about 80° wt % of the cosolvent, and from about 25 to about 55° wt-% of the basic copolymer. The basic copolymer can be dissolved in the oral composition, the oral composition is capable of forming a film on a surface when contacted with an aqueous solution; and the wt-% of each component is based on the total weight of the composition.Type: GrantFiled: September 27, 2019Date of Patent: September 15, 2020Assignee: 3M INNOVATIVE PROPERTIES COMPANYInventors: Yizhong Wang, Joel D. Oxman, Tiffany Ton
