Abstract:
Controlled radical initiators, reaction mixtures containing the controlled radical initiators and various ethylenically unsaturated monomers, polymeric materials formed from the reaction mixtures, crosslinkable compositions containing the polymeric materials, crosslinked compositions formed from the crosslinkable compositions, and various articles are provided. The controlled radical initiators are bis-dithiocarbamate or bis-dithiocarbonate compounds having a carbonyl group between the two dithiocarbamate or dithiocarbonate groups.
