HYDROPHOBIC DISPERSANTS USED IN FORMING POLYMER DISPERSIONS |
摘要 |
A process for the preparing a water soluble polymer dispersion which comprises polymerizing a water soluble mixture which comprises: (a) a cationic monomer represented by the general formula (I) as defined herein, and/or a second cationic monomer represented by the general formula (II) as defined herein; and (b) (meth)acrylamide in an aqueous solution of a polyvalent anion salt; wherein the polymerization is carried out in the presence of a hydrophobic dispersant which comprises a copolymer of diallyldimethylammonium chloride and a hydrophobic monomer.
