Patent number: 9815955Abstract: The present invention relates to blowing agent compositions comprising tetrafluoropropene (HFO) and at least one co-blowing agent selected from carbon dioxide, water, alkanes and an alcohol used in the preparation of foamable thermoplastic compositions having low density. The HFOs include, but are not limited too, cis- and/or trans-1,3,3,3-tetrafluoropropene (HFO-1234ze), 2,3,3,3-tetrafluoropropene (HFO 1234yf), or mixtures thereof. The blowing agent compositions are useful in the production of low density insulating foams with improved R value.Type: GrantFiled: January 28, 2010Date of Patent: November 14, 2017Assignee: Arkema Inc.Inventor: Brett L. Van Horn

Patent number: 9815956Abstract: An expandable composite resin bead containing an organic physical blowing agent and a base resin composed of a composite resin obtained by polymerizing a styrene monomer in a polypropylene resin. The styrene monomer is polymerized in an amount of more than 400 parts by mass and not more than 1900 parts by mass with respect to 100 parts by mass of the polypropylene resin. The composite resin contains xylene solubles to be obtained through xylene solvent Soxhlet extraction of the expandable composite resin bead, the xylene solubles contain acetone solubles to be obtained through dissolution of the xylene solubles into acetone, and the acetone solubles have an absorbance ratio A (D698/D1376) of an absorbance D698 to an absorbance D1376 that are respectively measured at a wavenumber of 698 cm?1 and 1376 cm?1 as infrared absorption spectra of the acetone solubles within a range of from 8.5 to 23.Type: GrantFiled: August 12, 2015Date of Patent: November 14, 2017Assignee: JSP CORPORATIONInventor: Masaomi Shima

Patent number: 9815957Abstract: Cellular and multi-cellular polystyrene and polystyrenic foams and methods of forming such foams are disclosed. The foams include an expanded polystyrene formed from expansion of an expandable polystyrene including an adsorbent comprising alumina, wherein the multi-cellular polystyrene exhibits a multi-cellular size distribution. The process for forming a foamed article includes providing a formed styrenic polymer and contacting the formed styrenic polymer with a first blowing agent and an adsorbent comprising alumina to form extrusion polystyrene. The process further includes forming the extrusion styrenic polymer into an expanded styrenic polymer and forming the expanded styrenic polymer into a foamed article.Type: GrantFiled: September 24, 2014Date of Patent: November 14, 2017Assignee: Fina Technology, Inc.Inventors: Jose M. Sosa, David W. Knoeppel

Patent number: 9815958Abstract: Polymeric porous particles have a continuous organic solid phase and at least two sets of discrete pores that are isolated from each other within the continuous phase and that have different average sizes. One set of discrete pores has a larger average size than another set of discrete pores by at least 50%. At least one set of discrete pores is free of detectably different marker materials. There porous particles can be prepared using evaporative limited coalescence techniques with especially chosen discrete pore stabilizing hydrocolloids to protect the pores during formation and to provide the different average sizes. The resulting porous particles can be incorporated into articles of various types and having various shapes.Type: GrantFiled: April 20, 2016Date of Patent: November 14, 2017Assignee: EASTMAN KODAK COMPANYInventors: David Charles Boris, Teresa Joy Hosmer, Mridula Nair

Patent number: 9815961Abstract: The invention relates to colorant compositions, and aqueous latex paints or other water-borne coatings made from them, which have a mitigated environmental impact. Levels of solvents, additives and impurities comprising volatile non-aqueous constituents, alkylphenol ethoxylates (and derivatives thereof), crystalline silica, and/or formaldehyde are decreased relative to those typical of preceding generations of colorants and tinted aqueous latex paints and other water-borne coatings. On the other hand, paint-performance as indicated by any of Stormer viscosity stabilization, rheological profile flow/leveling and sag resistance, water sensitivity and color transfer resistance is comparable to a paint in which the aforementioned solvents, additives and impurities are still present.Type: GrantFiled: September 3, 2015Date of Patent: November 14, 2017Assignee: Columbia Insurance CompanyInventors: Yong Yang, Mohammed Asif, Robert J.
