Abstract
Provided is a block copolymer film nanostructured in nanodomains, where the copolymer includes at least one first biodegradable block of polyester type and a second block of a different chemical nature than the first block. The first block of polyester type is polybutyrolactone (PBL) and the second block is derived from an oligomer or from a polymer bearing a hydroxyl function on at least one end and acting as macro-initiator of the polymerization of β-butyrolactone (β-BL) to give polybutyrolactone (PBL).
