摘要： A method of surface cross-linking superabsorbent polymer particles using UV irradiation is provided. The method is carried out in a so-called drum reactor, which comprises a hollow drum and an irradiation source. The drum has a longitudinal axis and a cross-section. Radical former molecules are applied on the surface of superabsorbent polymer particles. These superabsorbent polymer particles are fed into the drum and are irradiated while they move within the drum, which is rotated around its longitudinal axis. The irradiation source is provided such that the radiation emitted by the irradiation source is able to reach superabsorbent polymer particles within said drum. The irradiation source for use in the method is able to emit UV radiation of a wavelength between about 201 nm and about 400 nm.

摘要： An absorbent member for use in disposable diapers, wherein the absorbent member comprises a modified water absorbent resin. The modified water absorbent resin is made according to the method which comprises a) mixing a water absorbent resin and a water-soluble radical polymerization initiator or a heat-degradable radical polymerization initiator without addition of an ethylenically unsaturated monomer and b) irradiating the resultant mixture with active energy rays. The method is particularly capable of exalting the absorbency against pressure and the saline flow conductivity.
