Abstract

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.
