  • Patent number: 11697717
    Abstract: The invention relates to a method for the manufacture of a prophylactic article, especially of a glove, from a (carboxylated) diene rubber, according to which a layer of a (carboxylated) diene latex is applied on a former and the (carboxylated) diene latex is cross-linked with a cross-linking agent, which is immobilized on inorganic and/or organic particles with formation of modified particles, and the modified particles are added to the (carboxylated) diene latex.
    Type: Grant
    Filed: March 2, 2017
    Date of Patent: July 11, 2023

  • Patent number: 9894946
    Abstract: The invention relates to a method for modifying the surface of an elastomer product with unsaturated carbon-carbon bonds, in particular a glove, whereby the unsaturated carbon-carbon bonds in the region of the surface are at least partially saturated by a photochemical reaction with at least one thiol or by applying or dipping to apply a layer of latex to at least certain regions of the surface of the elastomer product, the unsaturated carbon-carbon bonds of which in the region of its surface are at least partially saturated by a photochemical reaction with at least one thiol.

  • Patent number: 9290632
    Abstract: The invention relates to a method of bonding particles to the surface of an elastomer, in particular a glove, the surface of the elastomer being at least partially epoxidized, and the particles are covalently bonded to the epoxide groups after epoxidation of the elastomer surface.

  • 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.
