  • Patent number: 9279038
    Abstract: Method for producing a cross-linked elastomer in which a mixture is produced comprising at least one latex and at least one starter component for initiating the cross-linking reaction or a latex that bears at least one starter component or starter group, in particular in liquid phase. A photoinitiator is used as a starter component, which photoinitiator, through irradiation with electromagnetic radiation in the ultraviolet (UV light) and/or visible spectral range forms a reactive species. The latex mixture is irradiated with UV light and/or visible light.

  • Patent number: 8673993
    Abstract: The invention relates to method for producing a crosslinked elastomer by radiating a polymer dispersion of at least one crosslinkable polymer with electromagnetic radiation in the ultraviolet (UV light) and/or visible spectral range, wherein the crosslinking is performed in at least two stages as pre-crosslinking and post-crosslinking and at least one photoinitiator is added to the polymer dispersion to trigger the crosslinking reaction prior to the pre-crosslinking. At least one photoinitiator is added once again to the pre-crosslinked polymer dispersion prior to and/or during the post-crosslinking, and the post-crosslinking is also performed with electromagnetic radiation in the ultraviolet (UV light) and/or visible spectral range.

  • Patent number: 6440498
    Abstract: The invention relates to an article, in particular a glove, a condom, or the like, which is comprised of a flexible rubber and/or plastic, is embodied having at least one section of the surface intended contact or rest against human skin, which article is provided with a slip coating in a section of the surface. This slip coating is comprised of a polymeric material and at least in sections, has repeating shape deviations of the surface that are recessed in relation to a raised, net-like structure. The ratio of the average spacings between the shape deviations to their depth in relation to the raised, net-like structure is between 500:1 and 5:1 and the average roughness depth is between 0.5 and 100 &mgr;m, preferably between 1 and 40 &mgr;m.
