Facile preparation of supramolecular (ABAC) n multiblock copolymers from Hamilton wedge and barbiturate-functionalized RAFT agents

Two original Hamilton wedge (HW)/barbiturate (Ba) functionalized symmetrical trithiocarbonates have been successfully synthesized and their capability to efficiently mediate the polymerization of styrene, n BuA and isoprene was investigated.

Summary:Two original Hamilton wedge (HW)/barbiturate (Ba) functionalized symmetrical trithiocarbonates have been successfully synthesized and their capability to efficiently mediate the polymerization of styrene, n BuA and isoprene was investigated. Relying on supramolecular association of the recognition couple, telechelic macromolecular building blocks subsequently afford the formation of novel supramolecular (ABAC) n multiblock copolymers, where A is in a glassy state, B and C in a rubbery state. The successful generation of the desired supramolecular structure was evidenced by 1 H NMR, ITC, viscometry, and DLS as well as DSC.
