| Abstract | 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.
The facile preparation of novel supramolecular (ABAC)
n
multiblock copolymers from Hamilton wedge and barbiturate functionalized H-bonding RAFT agents is reported. |
