Patent number: 11066498Abstract: A copolymer has low levels of cyclic oligomeric compounds, which are undesirable impurities in certain applications. The cyclic oligomeric compounds are provided in an advantageously low ratio of C21/C13 oligomers. The C13 oligomers are extractable using steam to further reduce the total amount of cyclic oligomers. A process for producing the copolymer having low levels of cyclic oligomers involves contacting at least one isoolefin monomer with at least one multiolefin and/or ?-pinene monomer in the presence of at least one Lewis acid and at least one initiator in a diluent. The diluent contains a hydrofluorinated olefin (HFO) comprising at least three carbon atoms and at least three fluorine atoms. Hydrofluorinated olefins used in the present invention are better diluents for butyl slurry cationic polymerization than saturated hydrofluorocarbons.Type: GrantFiled: April 28, 2015Date of Patent: July 20, 2021Assignee: ARLANXEO SINGAPORE PTE. LTD.Inventors: Paul Nguyen, Jessica Watson, Gilles Arsenault

Publication number: 20170139891Abstract: Information defining a first business information document, including a report element having a data provider and a variable, is received from a first user's device. The first document is saved in a central management system repository as a shared element, the shared element in the repository including an indication of the data provider and an indication of the variable. A request to access the shared element in the repository is then received from a second user's device. The shared element in the repository, including the indication of the data provider and the indication of the variable, are then incorporated within a second document for the second user. The shared element in the second document may be linked to the shared element in the repository such that a change to the shared element in the repository propagates to the shared element in the second document.Type: ApplicationFiled: November 13, 2015Publication date: May 18, 2017Inventors: Christian AH-SOON, Didier GROS, Bogdan RADULESCU, Stephane MONTAGNON, Anthony MULLER, Tin Jean-Paul NGUYEN, Alexis GUE

Patent number: 9644041Abstract: The present invention relates to a process for the production of halogenated butyl rubber and an apparatus for the production of rubber cement for use in the production of halogenated butyl rubber. The process and apparatus permit direct mixing of aqueous rubber slurry with a non-halogenated organic solvent to make a rubber cement solution. The water layer is then separated from the partially dissolved rubber cement and the cement phase is sent for halogenation. The apparatus is an enclosed vessel comprised of at least one dissolving zone and at least one separator zone. The process and apparatus advantageously employ recycle of rubber cement in order to disrupt an interface layer that forms between the water and rubber cement, to thereby improve continuously operation of the process.Type: GrantFiled: May 18, 2012Date of Patent: May 9, 2017Assignee: ARLANXEO Deutschland GmbHInventors: Tobias Groemping, Sven Bach, Baecker Werner, Wei Chen, Paul Nguyen, Kevin Alam, Robert Michael Wise, Thomas Mulder
