Abstract

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 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.
