Synthesis and Study of Thermoresponsive Amphiphilic Copolymers via RAFT Polymerization.

ABSTRACT: Synthesis and study of well-defined thermoresponsive amphiphilic copolymers with various compositions were reported. Kinetics of the reversible addition-fragmentation chain transfer (RAFT) (co)polymerization of styrene (St) and oligo(ethylene glycol) methyl ether methacrylate (PEO₅MEMA) was studied by size exclusion chromatography (SEC) and ¹H NMR spectroscopy, which allows calculating not only (co)polymerization parameters but also gives valuable information on RAFT (co)polymerization kinetics, process control, and chain propagation. Molecular weight M_n and dispersity Đ of the copolymers were determined by SEC with triple detection. The detailed investigation of styrene and PEO₅MEMA (co)polymerization showed that both monomers pref
