Abstract
PURPOSE: To prepare a water-soluble bead polymer useful as a flocculant, etc., with simplified dehydration process, by polymerizing an aqueous solution of a cationic (meth)acrylate monomer, etc. in an aromatic dispersing medium in the presence of a dispersion stabilizer.
CONSTITUTION: A bead polymer is prepared by polymerizing a composition comprising (A) a water-soluble vinyl monomer expressed by the formula (R1 is H or methyl; R2 and R3 are 1W4C alkyl; R4 is H, 1W4C alkyl or hydroxy-substituted alkyl, or benzyl; Y is 2W4C alkylene or hydroxy-substituted alkylene; X is halogen, etc.), and if necessary (B) a water-soluble vinyl monomer copolymerizable with (A) (e.g. acrylamide, etc.), (C) an oil-soluble cellulose ester or ether as a dispersion stabilizer, and (D) an aromatic hydrocarbon or a halogenated aromatic hydrocarbon as a dispersing medium, at ≥40°C.
