Abstract
The present invention has an object to provide an amphoteric polymer having high anti-soil redeposition ability and solubility with surfactants, and a process for producing the same. The amphoteric polymer includes: a structure unit (a) derived from a cationic group-containing monomer (A); and a structure unit (b) derived from a carboxyl group-containing monomer (B). The structure unit (a) is present at a level of 1 to 99% by mass based on 100% by mass of all structure units derived from all monomers in the amphoteric polymer, and the structure unit (b) is present at a level of 1 to 99% by mass based on 100% by mass of all the structure units derived from all the monomers in the amphoteric polymer.
