Post-polymerization modification of polymer chain-ends is a powerful tool for the preparation of functional materials. "Click" type reactions represent the most prevalent post-polymerization strategies. We applied the recently described sulfur(VI) fluoride exchange reaction to functionalize the chain-ends of four polymers prepared using activators generated by electron transfer atom transfer radical polymerization. Aryl-TBDMS terminated polymers were reacted with aryl sulfurofluoridate compounds with a near quantitative conversion. This research represents the application of a new click type reaction to prepare functional polymers. (C) 2015 Elsevier Ltd. All rights reserved.
