Abstract

Hollow polymer capsules were prepared from linear as well as brushlike poly(2-oxazoline)s (POxs). Linear POxs containing alkene functionalities were obtained by cationic ring-opening polymerization (CROP), whereas the brush POxs bearing alkyne moieties were synthesized by a combination of CROP and reversible addition-fragmentation chain transfer (RAFT) polymerization. Multilayers consisting of POx/poly(methacrylic acid) (PMA) were sequentially deposited onto silica particle templates, and the films were stabilized either by thiol-ene (TE) chemistry or copper-catalyzed azide-alkyne cycloaddition (CuAAc). Stable, monodisperse capsules were formed after removal of the silica particles with hydr..
