POLYMER DISPERSION AND METHOD OF PREPARING SAID DISPERSION Russian patent published in 2010 - IPC C08F283/00 C08F290/06 C08G73/02 D21H17/45

Abstract RU 2394846 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a method of preparing an aqueous polymer dispersion. The method involves reacting one or more cationic or non-ionic monomers (m) and a polymer (B) in the presence of a co-stabiliser A. Polymer (B) is hydrolysed in the presence of a co-stabiliser (A) with formation of a polymer stabiliser (C). The obtained aqueous dispersion is further used as a holding agent in paper production.

EFFECT: disclosed dispersion demonstrates good retention and dehydration properties.
