  • Water soluble acrylic membrane-polymer protein amphiphilic complex and application to diagnosis methods
    Patent number: 6492501
    Abstract: The invention concerns a water soluble vinyl membrane-polymer protein amphiphilic complex, characterised in that said vinyl polymer corresponds to formula (I) in which: R1 is a group: COO⊖ M+ M+ being an alkaline cation, COOR7, R7 being a sugar radical; polyoxyalkylene, polyoxyethylene; N-pyrrolidonyl; phenyl sulphonate; CONR8R9, R8 and R9 identical or different being hydrogen atom, a sugar radical, polyoxyalkylene, in particular polyoxyethylene, a zwitterion radical; R4, R5, R6 identical or different are hydrogen atom, or methyl radical; R2 is a COOR12 or CONR13R14 radical, R12 being a linear or branched alkyl or alkylene radical; R13, R14 identical or different have one of the meanings of R12, and moreover one of the two can correspond to hydrogen atom; R3 is a COOR15 or CONR16R17 radical; R15 being a (C1-C5) alkyl radical; R16, R17 having one if the meanings of R15 and moreover one of the two can correspond to hydrogen atom; x, y, z correspond to the respective percentages of units.

  • Process for preparing an aqueous composition in gel form and compositions obtainable from this process, especially a composition containing vesicles, in particular liposomes
    Patent number: 6469084
    Abstract: The present invention concerns a process for preparing an aqueous composition in the form of a gel at a given temperature. The process is characterized in that an associative water-soluble polymer constituted by a hydrophilic main chain and hydrophobic pendant groups is brought into the presence, in said composition, of at least one surfactant in the form of bilayers when it is in aqueous solution under the same temperature and concentration conditions. Compositions in the form of gels or liquids are thus obtained.

  • Cement composition containing chemically crosslinked polyvinyl alcohol (PVA)
    Patent number: 5594050
    Abstract: The invention relates to a new, chemically crosslinked PVA. Its application is that of a fluid loss control agent in fluids used in the oil industry, in particular cement slurries, separating fluids, or "spacers", and drilling muds. Its advantages are that it does not delay the setting of the cement, that it has high temperature properties that are relatively insensitive to external conditions.
