Synthesis and Post‐Polymerization Modification of Defined Functional Poly(vinyl ether)s

Living cationic polymerization is known for a good control over chain growth yielding polymers with well-defined molar mass distributions and low dispersities. However, the practical challenges involved in synthesis of poly(vinyl ether)s limited suitable post-polymerization modifications (PPM) via chemoselective click reactions. Herein successful controlled vinyl ethers bearing pendant CC double C≡C triple bonds using single-component initiation under ambient conditions reported. Furthermore, PPM thiol-ene/-yne copper(I)-catalyzed alkyne-azide cycloaddition reaction obtained successfully realized laying foundation unprecedented functional ether)s.
