Abstract
Crosslinkable compositions are provided that contain a) a polymeric material having at least two terminal dithiocarbamate groups or two terminal dithiocarbonate groups and b) a monomer composition that includes at least a crosslinking monomer having two or more ethylenically unsaturated groups. The polymeric materials in the crosslinkable compositions undergo chain extension and crosslinking reactions when exposed to actinic radiation in the ultraviolet region of the electromagnetic spectrum. Additionally, crosslinked compositions, articles that contain the crosslinkable compositions or the crosslinked compositions, and methods of making the articles are provided.
