Block copolymers of 1 H ,1 H ,2 H ,2 H ‐perfluorodecyl acrylate (AC8) were obtained from ARGET ATRP. To obtain block copolymers of low dispersity the PAC8 block was synthesized in anisole with a CuBr 2 /PMDETA catalyst in the presence of tin(II) 2‐ethylhexanoate as a reducing agent. The PAC8 block was subsequently used as macroinitiator for copolymerization with butyl and tert‐ butyl acrylate carried out in scCO 2 . To achieve catalyst solubility in CO 2 two fluorinated ligands were employed. The formation of block copolymers was confirmed by size exclusion chromatography and DSC.
