    摘要: A method of surface cross-linking superabsorbent polymer particles having a relatively high degree of neutralization is provided. Brønsted acids are selectively applied onto the surface of the superabsorbent polymer particles to selectively facilitate a relatively high number of protonated carboxyl groups at the surface of the superabsorbent polymer particles while the relatively high degree of neutralization in the core of the superabsorbent polymer particles remains substantially unaffected.

    摘要: The present invention relates to superabsorbent polymer particles having functionalizers covalently bound to the surface of precursor superabsorbent polymer particles. The functionalizers of the present invention comprise a grafting unit with a radiation activatable group and a functional unit covalently bound to the grafting unit. The grafting unit is bound to an aliphatic C—H group comprised at the surface of the precursor superabsorbent polymer particle. The functional unit comprises chemical structures which are not present in the precursor superabsorbent polymer particle. These functional units add an additional function to the precursor suberabsorbent polymer particle or modifying an existing function of the precursor superabsorbent polymer particle. Moreover, the invention relates to a process for making these superabsorbent polymer particles.

    摘要: Superabsorbent polymer particles with improved surface cross-linking and their use in absorbent articles. The superabsorbent polymer particles comprise polymer chain segments, wherein at least a part of the polymer chain segments are covalently cross-linked to each other and wherein at least a part of the cross-links include the reaction product of cross-linking molecules having at least two C═C double bonds and further include the reaction product of radical former molecules. These cross-links are present at surfaces of the superabsorbent polymer particles.

    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.
