Abstract
Brush-shaped macromolecular architectures provide unique material properties because of their dense branched structures. However, there are major challenges in obtaining brush-shaped macromolecules when the required functional monomers are not compatible for copolymerization using the same synthetic technique. Herein, we present an inimer molecule structure that has both an initiating group for Cu-mediated radical polymerization and a 2-oxazoline monomer ring for cationic ring-opening polymerization. Thus, various combinations of poly(2-oxazoline-brush-acrylate/acrylamide) copolymers could be obtained by grafting from a poly(2-oxazoline) backbone bearing radical initiator units. A simple two-step synthesis method for a novel 2-oxazoline inimer was established and used in the homo and block copolymerization with 2-ethyl-2-oxazoline to yield the brush initiator structure. Moreover, selected acrylates and acrylamides were utilized for Cu(0)-mediated reversible deactivation radical polymerization (RDRP) initiated through the brush initiator. Finally, because of the understanding obtained via optimization reactions, high/low density, block, and amphiphilic brush copolymers with narrow molecular weight distributions were successfully obtained.
