Described herein is a fluorinated block copolymer having (a) at least one A block, wherein the A block is a semi-crystalline segment comprising repeating divalent monomeric units derived from at least a fluorinated monomer, and a cure-site monomer; (b) at least one B block, wherein the B block is a segment comprising repeating dilvalent monomeric units derived from at least a fluorinated monomer. L'invention concerne un copolymère séquencé fluoré comportant: a) au moins un bloc A qui est un segment semi-cristallin comprenant des unités monomères divalentes récurrentes dérivées d'au moins un monomère fluoré, et un monomère de site de durcissement; b) au moins un bloc B qui est un segment comprenant des unités monomères divalentes récurrentes dérivées d'au moins un monomère fluoré.
