Patent number: 8673993Abstract: 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.Type: GrantFiled: March 17, 2010Date of Patent: March 18, 2014Assignee: Semperit Aktiengesellschaft HoldingInventors: Armin Holzner, Wolfgang Kern, Raimund Schaller, Sandra Schloegl
