CA 2608408

The present invention relates to a process for preparing a polymer dispersion comprising polymerising one or more water soluble anionic monomers (m1) and one or 5 more non-ionic vinyl monomers (m2) present in a reaction mixture further comprising a polymeric stabiliser (B) and a polymeric co-stabiliser (C). It further relates to a polymer dispersion, the use of the polymer dispersion and a process for producing paper.

La présente invention concerne un procédé d'élaboration de dispersion de polymères par polymérisation d'au moins un monomère anionique hydrosoluble (m1) et d'au moins un monomère de vinyle non ionique (m2) présents dans un mélange de réaction comprenant également un stabilisant polymère (B) et un co-stabilisant polymère (C). L'invention concerne également une dispersion de polymères, l'utilisation de cette dispersion, et un procédé de production de papier.
