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.

Polymers, the process for their preparation and the invert latexes containing them

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.
