  • Pyrimidine derivatives
    Patent number: 11439148
    Abstract: This invention relates to pyrimidine derivatives, to compositions comprising the pyrimidine derivatives, to methods of making and using these compositions, and to the use of the pyrimidine derivatives as adjuvants, particularly for agrochemical use. In particular, the present invention relates to compositions comprising the pyrimidine derivatives selected from emulsifiable concentrates (EC), emulsions in water (EW), suspensions of particles in water (SC), soluble liquids (SL), capsule suspensions (CS), suspensions of particles with an emulsion (SE), dispersion concentrates (DC), suspensions of particles in oil (OD), water dispersible granules (WG), soluble granules (SG) and wettable powders (WP).
    Type: Grant
    Filed: November 26, 2018
    Date of Patent: September 13, 2022
    Assignee: SYNGENTA PARTICIPATIONS AG
    Inventors: Niall Rae Thomson, Gordon Alastair Bell, Philip Taylor, Julia Lynne Ramsay, Stephanie Lucas, Renaud Perrin, Stephen Christopher Smith

  • Method for preparing proton-conducting inorganic particles
    Patent number: 9227187
    Abstract: The invention relates to a method for functionalization of inorganic particles by polymers comprising at least one recurrent unit bearing at least one proton exchange group comprising the following steps: a) a step for functionalization of inorganic particles by an anionic polymerization termination agent comprising at least one group capable of being bound to the surface of said particles; b) a step for anionic polymerization of at least one monomer bearing at least one precursor group of a proton exchange group; c) a step for putting the particles obtained in step a) in contact with the polymers obtained in step b), in return for which the obtained particles are particles functionalized by said polymers by reaction between a reactive end of said polymeric polymers and at least one group of the aforementioned termination agent; and d) a step for transformation of the precursor group(s) of said proton exchange group(s).

  • Sulfonated polymers useful for forming fuel cell membranes
    Patent number: 9184459
    Abstract: The invention relates to a polymer comprising at least one polymeric chain of a first type, the said chain comprising at least two blocks, the same or different, the said blocks comprising repeat units derived from the polymerisation of styrene monomers, the said units comprising at least one phenyl pendant group carrying at least one —SO3R group, R possibly being a hydrogen atom, an alkyl group or cationic counter-ion, the said two blocks being separated by a spacer group, the spacer group is a perfluorocarbon group.
