Abstract
Crosslinkable polymeric materials, crosslinked polymeric materials, articles containing the crosslinkable polymeric materials or crosslinked polymeric materials, and methods of making the articles and various compositions are provided. More particularly, the crosslinkable composition contains a) a first polymeric material, which has terminal dithiocarbamate or dithiocarbonate groups, b) a crosslinking composition containing a chlorinated triazine crosslinking agent and/or a crosslinking monomer having two or more ethylenically unsaturated groups, and c) a thixotropic agent containing metal oxide particles. The crosslinkable composition may be printable or dispensed. In some embodiments, the crosslinked composition is a pressure-sensitive adhesive.
