摘要：
A supramolecular ABC-type miktoarm star polymer was prepared using a Hamilton wedge (HW) mid-chain functionalized polyethylene glycol-b-polystyrene (PEG-HW-PS) block copolymer and an alpha-cyanuric acid (CA) chain-end functional linear homopolymer poly(n-butylacrylate) (CA-PnBA). The PEG-HW-PS element prepared via a combination of atom transfer radical polymerization (ATRP) and copper-catalyzed azide alkyne cycloaddition (CuAAC) (M-n = 13,700 g mol(-1), PDI = 1.04). The CA-PnBA strand was synthesized via reversible addition-fragmentation chain transfer (RAFT) polymerization (M-n = 11,300 g mol(-1), PDI = 1.06). The quantitative formation of a well-defined supramolecular ABC-type miktoarm star polymer was unambiguously proven via proton nuclear magnetic resonance (H-1 NMR) spectroscopy, diffusion ordered NMR spectroscopy (DOSY) and dynamic light scattering (DLS) analyses.
