    Abstract: The present invention relates to functionalizing a surface of an organic material. For example, surfaces of materials having C—H bonds, such as polymers having C—H bonds, can be functionalized. In certain embodiments, a heterobifunctional molecule having a photoactive anchor, a spacer, and a terminal functional group is applied to the surface of an organic material that contains one or more C—H bonds. The heterobifunctional molecule can be bound to any surface having C—H bonds as the photoactive anchor can react with C—H bonds upon irradiation. The terminal functional group has a “click” functionality which can be utilized to functionalize the surface of the organic material with any desired functionalizing moiety having the orthogonal click functionality.

  • Publication number: 20080207792
    Abstract: The present disclosure relates to a method of surface treating particulate materials with electromagnetic radiation, in particular a method of cross-linking superabsorbent polymer particles using UV irradiation. The method is carried out with a so-called roll reactor, which comprises a rotating roll and an irradiation source. Radical former molecules can be applied on the surface of superabsorbent polymer particles. The particulate material is fed onto the surface of the roll and is irradiated while moved with the rotating roll. The irradiation source is provided such that the radiation emitted by the irradiation source is able to reach at least part of the particulate material that has been fed onto the surface of the roll. The irradiation source for use in the method of the present disclosure is able to emit UV radiation of a wavelength between 201 nm and 400 nm. The present disclosure also relates to absorbent articles comprising surface treated superabsorbent particles made by said method.
