Abstract: A hydrocolloid polymer and sorbent article containing same are disclosed. The polymer is prepared from a reaction mixture that consists essentially of (a) about 80 to about 100 mole percent water-soluble alpha, beta-monoethylenically unsaturated monocarboxy monomer containing a chain of three carbon atoms, (b) zero to about 20 mole percent water-soluble copolymerizable monoethylenically unsaturated monomer, (c) zero to about 3 percent of a copolymerizable polyethylenically unsaturated cross-linking agent, and (d) about 10 to about 25 percent by weight glycerol based upon the ethylenically unsaturated species present. The sorbent article comprises a water-insoluble fibrous web matrix having the hydrocolloid polymer coated thereon. The polymer and polymer-coated web exhibit improved water sorption and flexibility.
