Functional polymers were successfully prepared in scCO(2) by combining alkyne-azide 1,3-dipolar Huisgen's cycloaddition and dispersion ATRP in a "one-pot" process using new perfluorinated polymeric amino-based ligands that had a dual role, i.e. the complexation of the copper catalyst and the stabilization of growing particles.
