Monomer-controlled self-switchable polymerization: a metal-free strategy for synthesizing multiblock copolymers from epoxides, O-phthalaldehyde, and CO₂

Abstract

Advances in chemoselective ring-opening polymerization have enabled the preparation of copolymers with precisely controlled chain structure. However, the building blocks for the sequence-controlled polymers are mostly limited to polyether, polycarbonate...
