Equipment for preparing a polymer solution of a non-ionic, cationic, anionic or amphoteric polymer by reaction between a compound including at least one aldehyde function and at least one base polymer aqueous solution having at least one non-ionic monomer includes a reactor provided with a stirring system, as well as a recirculation loop including between the outlet of the reactor and the inlet of the reactor, a recirculation pump, a pH measuring probe, and a pressure differential in-line measuring device in the form of a calibrated tube configured to measure the pressure difference of the polymer solution between the inlet and the outlet of the calibrated tube, the calibrated tube being branched on the recirculation loop.

Equipment and method for preparing an aldehyde-functionalised polymer

Polymer complex obtained by polymerization of water-soluble monomers: in the presence of a host polymer comprising vinylamine functions and of a non-polymeric transfer agent, and in the absence of branching or crosslinking agent of ethylenic polyfunctional type.
