  • Polymers, the process for their preparation and the invert latexes containing them
    Patent number: 6531561
    Abstract: Linear, branched or crosslinked polymer, capable of being obtained by polymerization of N-alkylacrylamide, in which the alkyl radical is linear or branched and comprises from 1 to 6 carbon atoms, with one or more monomers chosen from cationic monomers, monomers comprising at least one partially salified or completely salified strong acid functional group or monomers comprising at least one partially salified or completely salified weak acid functional group. A method of preparing the polymer is also disclosed.
    Type: Grant

  • Associative polymers containing 2,4,6-triphenethyl benzyl poly(ethoxy)(meth)acrylate as a monomer and their process of preparation by inverse emulsion polymerization
    Patent number: 6107398
    Abstract: Novel associative acrylic polymers prepared by radical inverse emulsion polymerization. It is a methacrylic ester in which the radical is composed of a hydrophilic segment and of a hydrophobic segment. The associative polymers of the invention can be used as thickeners, flocculating agents or filler-retaining agents.
