ABSTRACT:
Superabsorbents are produced by polymerization in the presence of at least one unsaturated polyetherol selected from the group consisting of polyetherols having the following structural formulae (1), (2), (3) and (4):where n is 0 or 1,m is 1, 2, 3, 4, 5 or 6,o is a natural number from 1 to 200, andA is —(H2C—CHR1—O)— or —(R1HC—CH2—O)—, where R1in each occurrence is independently hydrogen or an organic radical.
