ABSTRACT:
A composition which comprises a water-polymer and a process for using the polymer to absorb a fluid are disclosed. The water-insoluble polymer comprises repeate units derived from: (a) an ampholytic monomer which is a polymerizable vinylic amine-containing monomer and an acid having an ethylenic moiety; (b) at least one olefinic comonomer; and optionally, (c) one crosslinking agent which has at least two polymerizable olefinic functionalities wherein the olefinic functionalities are suitable for crosslinking.
