Redox polymerization method, water-absorbent resin composite, and absorbent article

摘要

In a method of redox polymerization of monomer by the use of a non-metal reducing agent and a non-metal oxidizing agent, a transition metal compound is used in addition to the reducing agent and the oxidizing agent in an amount of from 0.01 to 100 ppm by weight in terms of the metal thereof relative to the monomer, whereby the polymerization speed is significantly increased. Using this, water-absorbent resin composite and an absorbent article can be produced.
