Abstract
Silicone-based pressure-sensitive adhesives, reaction mixtures used to form the pressure-sensitive adhesives, methods of making the silicone-based pressure-sensitive adhesives, and articles containing the silicone-based pressure-sensitive adhesives are described. More particularly, the silicone-based pressure-sensitive adhesives include silicone-based elastomeric materials that are prepared by polymerizing a silicone compound having at least two ethylenically unsaturated groups in the presence of actinic radiation (e.g., ultraviolet radiation) and a controlled radical initiator. The controlled radical initiator is a bis-dithiocarbamate or bis-dithiocarbonate compound having a single carbon between the two dithiocarbamate or dithiocarbonate groups.
