ABSTRACT:
A method of treating starch-containing water comprises the step of adding water swellable, cationic polymerizate particles to the starch-containing water. The starch is soluble starch. The water-swellable cationic polymer particles are polymer particles of a crosslinking monomer and either a cationic vinyl monomer or a cationic vinyl monomer and a nonionic vinyl monomer.
