Chain Transfer Agent for Controlled Cationic RAFT Polymerization of Vinyl Ethers
Tetrahydrofuran-2-yl Pyrrolidine-1-carbodithioate (T4405) is a RAFT agent (reversible addition–fragmentation chain-transfer) suitable for cationic RAFT polymerization. In contrast to many other RAFT agents, T4405 is a solid at room temperature, making it easy to handle.²) In cationic RAFT polymerization, the reaction proceeds through a RAFT mechanism similar to that of standard RAFT polymerization, but the intermediates are cationic rather than radical.¹) Controlled polymerization of vinyl ethers and electron-rich styrenes is typically achieved using a Brønsted acid as initiator in combination with an appropriate RAFT agent.²)³) For example, polymerization of isobutyl vinyl ether (I0099) with 1-Isobutoxyethyl Diethylcarbamodithioate (I1322) and trifluoromethanesulfonic acid (T0751) as initiator at a ratio of 500 : 10 : 0.05 gave Mn 5200 and Mw/Mn 1.07.³) Switching from or combining with radical RAFT polymerization also enables the synthesis of polymers with specialized structures.
