ABSTRACT:
There is disclosed an ampholytic polymer capable of absorbing aqueous electrolyte solutions, which is obtainable by polymerization of a monomer mixture including (A) at least 10 mol % of an ampholytic vinyl monomer, with the proviso that when the monomer (A) has no self-crosslinkability, the amount of monomer (A) is in the range of 10 to 99.995 mol %. The monomer mixture may further include (B) 90 mol % or less of a non-ampholytic vinyl monomer and (C) 1 mol % or less of a crosslinkable monomer, with the proviso that the total amount of monomers (A), (B) and (C) is 100 mol % and when the monomer (A) has no self-crosslinkability, the amount of monomer (C) is in the range of 0.005 to 1 mol %.
