摘　　要：Post-polymerization modification provides an important approach to tuning the material properties of obtained polymers.In this work,we demonstrated a rational design of novel vinylcyclopropane monomer bearing a pendant N-hydroxylphthalimide redox ester,and explored its radical ring-opening polymerization behavior under visible-light conditions.Photochemical decarboxylation of resulted polymer provided unique access to poly(vinylcyclopropane)bearing single ester group in each repeating unit.This decarboxylative modification has greatly reshaped the thermal and mechanical properties,converting a glassy polymer into a soft,ductile,and rubber-like material.
