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.

Patent number: 8541511Abstract: The invention relates to an amphiphilic block copolymer having an increased speed of water adsorption. The non-water soluble copolymer, having a hydrophilic middle block and hydrophobic endblocks, has a high rate water transmission and/or permeation. The increase in rate is due to neutralization, or partial neutralization of the hydrophilic block of the copolymer. Furthermore, the absorption rate can be controlled by the extent of the neutralization. Another aspect of the invention is the use of co-monomers and/or additives to further increase or tailor the water absorption properties. The use of additives and comonomers is also shown to enhance the processability of the disclosed polymer composition.Type: GrantFiled: June 15, 2009Date of Patent: September 24, 2013Assignee: Arkema Inc.Inventors: Scott C. Schmidt, Noah E. Macy, Jean-Pierre Disson

Publication number: 20110301298Abstract: The present invention relates to a class of acid functionalized gradient block copolymers, processes for obtaining them and to their uses including but not limited to hair fixatives, toughening agents, and adhesives. Surprisingly, the applicants have discovered the aforementioned class of acid functionalized gradient block copolymers have advantageous properties and can find utility in a wide variety of application areas. These polymers are easily prepared by sequential monomer addition (i.e., “one-pot” synthesis) and the process does not require any post polymerization modification steps. The aforementioned polymers are derived from commonly utilized monomers. The use of common monomers provides both an economic advantage and an inherent safety advantage, e.g., the common monomers are considered biocompatible.Type: ApplicationFiled: August 15, 2011Publication date: December 8, 2011Applicant: Arkema Inc.Inventors: Scott C. Schmidt, Peter A. Callais, Noah E. Macy, Jason S. Ness
