Thiyl radical reversible-deactivation polymerization <i>via</i> degenerative transfer with vinyl sulfides.

ABSTRACT: Precise control over thiyl radical polymerizations remains a significant challenge in polymer chemistry, particularly within the framework of traditional reversible-deactivation radical polymerization (RDRP) techniques. In this work, we introduce a novel thiyl radical reversible-deactivation polymerization (SRDP) strategy that employs vinyl sulfides as degenerative transfer agents to reversibly deactivate the propagating thiyl radicals, thus enabling direct and efficient control over the thiyl radical polymerizations to afford polymers with tunable molecular weights and low dispersities. The controlled nature of this polymerization was further confirmed by first-order kinetics, a linear relationship between molecular weight and conversion, and efficient chain extension. In addition, densit
