Abstract:
Provided are a preparation method of a superabsorbent polymer, and a superabsorbent polymer prepared thereby. The preparation method of the superabsorbent polymer according to the present disclosure enables preparation of the superabsorbent polymer which is excellent in absorption properties such as centrifuge retention capacity and absorbency under pressure, and also has improved permeability. In addition, the preparation method exhibits excellent operability during the preparation (in particular, surface crosslinking of the polymer) and excellent productivity due to low production of coarse particles and fine particles.

Claim (Index 1):
A superabsorbent polymer comprising a crosslinked polymer formed by polymerization and internal crosslinking of water-soluble ethylene-based unsaturated monomers and a polycarboxylic acid-based copolymer having repeating units represented by the following Chemical Formula 1-a and Chemical Formula 1-b, which is present on the crosslinked polymer: wherein, in Chemical Formula 1-a and 1-b, R 1 , R 2 , and R 3  are each independently hydrogen or an alkyl group having 1 to 6 carbon atoms, RO is an oxyalkylene group having 2 to 4 carbon atoms, M 1  is hydrogen or a monovalent metal or non-metal ion, X is \u2014COO\u2014, an alkyloxy group having 1 to 5 carbon atoms, or an alkyldioxy group having 1 to 5 carbon atoms, m is an integer of 1 to 100, n is an integer of 1 to 1000, and p is an integer of 1 to 150, and provided that there are two or more of p, two or more repeating (\u2014RO\u2014)s may be the same as or different from each other.
