This article describes for the first time the pseudo‐living radical activity of 4‐vinyl‐1,3‐dioxolane‐2‐one (VEC) monomer towards a free radical homo‐polymerization: a kinetic study of VEC homo‐polymerization was performed up to 168 hours and it was found that molecular weights, determined via gel permeation chromatography (GPC), and VEC conversion, measured via 1 H NMR spectroscopy, continue to grow over time showing a molecular weights distribution typical of pseudo‐living polymerizations. Until today, in co‐polymerization with styrene, just a few VEC moieties could be inserted into VEC‐styrene co‐polymers; in this work VEC controlled radical activity allows, for the first time, the synthesis of di‐block co‐polymers between styrene and vinyl groups bearing cyclic carbonate functionalities that can be used for further cross‐linking reactions. VEC‐styrene co‐polymers were synthesized with different molar ratios between co‐monomers and characterized by GPC analyses and 1 H NMR spectra; excellent reaction yields and solubility in apolar solvents were obtained.
