Patent number: 9587107Abstract: The invention relates to heat treatment of polymorphic semicrystalline or crystallizable polymers to increase the content of the highest melting crystalline form. Such heat treatment results in a polymer powder that has a consistent, uniform melting range, improved flow and improved durability of the powder particle size for applications that require powder flow at elevated temperatures. In addition to improved powder properties, the articles produced from the powders also exhibit better physical properties in both appearance and in mechanical properties. Thus the invention also includes polymer powders and articles produced by the described processes.Type: GrantFiled: September 27, 2011Date of Patent: March 7, 2017Assignee: Arkema Inc.Inventors: Christopher A. Bertelo, Manuel A. Garcia-Leiner, Anthony Decarmine, Scott F. Defelice

Publication number: 20160233825Abstract: A nanodiamond coating for use on a solar cell, the coating including a nanodiamond material suspended in a liquid, wherein the nanodiamond material has a size range from about 1 nm to about 10 nm. Methods for improving the efficiency of a solar cell are provided, including, mixing a nanodiamond material with a liquid polymer or non-polymer solvent to form a nanodiamond-polymer suspension, forming a coating of the suspension on a top surface of a solar cell, and drying the coating such that a dried nanodiamond-polymer layer remains bonded to the solar cell. Useful nanodiamond coating compositions may include a nanodiamond material, a fluoropolymer, a liquid solvent for the fluoro-polymer and at least one additive selected from the group consisting of dispersing agents, adhesion promoters, and coupling agents. The fluoropolymer may also be used in the form of an aqueous dispersion.Type: ApplicationFiled: September 23, 2014Publication date: August 11, 2016Inventors: Christopher A. Bertelo, Scott R.

Patent number: 9062236Abstract: The present invention relates to polymeric oil-return agents which solubilize or disperse mineral oil and/or synthetic oil lubricants with hydrofluorocarbon, hydrochlorofluorocarbon, and hydrofluoroolefin-based refrigerants and refrigerant compositions containing them. The polymeric oil-return agents are random copolymers containing less than about 30 wt % fluorine and produced from at least one monomer providing compatibility with the oil phase and at least one monomer providing compatibility with the refrigerant phase. The polymeric oil-return agents provide for more efficient return of mineral oil and/or synthetic oil lubricants from non-compressor zones back to a compressor zone in a refrigeration system.Type: GrantFiled: October 27, 2010Date of Patent: June 23, 2015Assignee: Arkema Inc.Inventors: Brett L.
