Patent number: 9078837Abstract: The invention relates to polymer particles in the form of filaments formed by block copolymers, as well as to the use thereof as rheology modifiers for aqueous or organic solutions. A first aspect of the invention relates to filamentous polymer particles having a length/diameter ratio greater than 100, said particles being formed by block copolymers synthesized by controlled radical emulsion polymerization in emulsion, performed using at least one hydrophobic monomer in the presence of a water-soluble marcoinitiator. The invention is characterized in that the filamentous particles are obtained in an aqueous medium for the synthesis of said block copolymers, performed by heating the reaction medium to a temperature of 60 to 120° C., the final block copolymer containing between 10 and 50 mol. % of the water-soluble macroinitiator and the hydrophobic monomer conversion rate being at least 50%.Type: GrantFiled: December 22, 2011Date of Patent: July 14, 2015Assignees: Arkema France, Universite Pierre et Marie Curie, Centre National De La Recherche Scientifique, Universite Claude Bernard Lyon, Ecole Superieure de Chimie Physique Electronique de LyonInventors: Stephanie Magnet, Raber Inoubli, Laurence Couvreur, Bernadette Charleux, Segolene Brusseau

Publication number: 20150126667Abstract: The present invention discloses a block copolymer comprising a block with glass transition temperature higher than 100° C. and a method for preparing the same. In the method, latex of a block copolymer is prepared by taking n-butyl acrylate as a soft block, random copolymer of styrene and ?-methyl-?-methylene-?-butyrolactone as a hard block, utilizing emulsion polymerization system and reversible addition fragmentation chain transfer radical polymerization technology. The method utilizes an amphiphilic macromolecule reversible addition fragmentation chain transfer agent has dual function of both chain transfer agent and emulsifier, thus can achieve good control of monomer polymerization and avoid the use of traditional emulsifier; the reaction has no polymerization inhibition period, has fast reaction rate and high final conversion; colloidal particles can stably grow; product has a hard block with glass transition temperature up to 155° C.Type: ApplicationFiled: January 10, 2015Publication date: May 7, 2015Inventors: SHAOHONG XU, Xiang Gao, Yingwu Luo

Patent number: 8993668Abstract: What are described are polyvinyl ester dispersions which are prepared in a multistage process and have a low content of polymerized acids or acid anhydrides. They can be obtained by a multistage process in which a polyvinyl ester dispersion is obtained in a first stage, monomers in dissolved or pure form are added to the reaction mixture in a second stage and then the polymerization is started again. The polymer dispersions obtained in this way are notable for a low coagulum content and for increased tensile strengths of the films formed therefrom.Type: GrantFiled: July 15, 2008Date of Patent: March 31, 2015Assignee: Celanese Emulsions GmbHInventor: Ivan Cabrera
