Enabling Reversible Addition-Fragmentation Chain-Transfer Polymerization for Brush Copolymers with a Poly(2-oxazoline) Backbone

The combination of different monomer classes has been sought after to access a wider range brush copolymers owing their unique properties derived from dense macromolecular structures. Herein, we report the synthesis 2-oxazoline (RAFTOx) containing chain transfer agent at 2-position and its subsequent utilization in reversible addition-fragmentation chain-transfer (RAFT) polymerization. With aim tuning density these polymers, homopolymers, block copolymers, gradient various ratios with 2-ethyl-2-oxazoline RAFTOx have prepared. Selected macroCTAs were then used for RAFT polymerization N,N-dimethylacrylamide 2-ethyhexyl acrylate prepare architectures.
