Title:
ポリマー分散液の形成における疎水性分散剤
Document Type and Number:
Japanese Patent JP3554023
Kind Code:
B2
Abstract:
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 and a hydrophobic dispersant used in forming polymer dispersions which comprises a copolymer of diallyldimethylammonium chloride and a hydrophobic monomer selected from the group consisting of: dialkylaminoalkylacrylates having C6 to C20 quaternaries, dialkylaminoalkylmethacrylates having C6 to C20 quaternaries, dialkylaminoalkylacrylamides having C6 to C20 quaternaries, dialkylaminoalkylmethacrylamides having C6 to C20 quaternaries, and alkyl esters of acrylic acid.
