Self-Switchable Polymerization: A Smart Approach to Sequence-Controlled Degradable Copolymers

In the quest for sustainable development, degradable polymers are attractive alternatives to traditional fossil-based plastics. As monocomponent often suffer from unsatisfactory performances, utilization of corresponding copolymers with tailored block compositions is viable improved properties. To this end, emerging field self-switchable polymerization offers a facile access on-demand synthesis controlled sequences, in which polymerizations were regulated by monomers themselves. This Perspective outlines state-of-the-art systems based on ring-opening (co)polymerization various types monomers. The scope catalysts and monomer summarized. Comprehensive comparison between different offered along an outlook possible future.
