Substrate comprising a surface coated with an epilamization agent and method for epilamization of such a substrate

A substrate comprising a surface at least one part of which is coated with an epilamization agent, wherein said epilamization agent comprises at least one compound in the form of a statistical copolymer consisting of M units, N units and optionally at least one P unit, linked by covalent bonds by their main chains and randomly distributed, where

• M is
• N is
• P is
• where R1, R2, R3, which may be identical or different, are H, a C1-C10 alkyl group, a C1-C10 alkenyl group,
• Y, X, which may be identical or different, are spacer arms formed of a heteroatom or of a linear or branched hydrocarbon chain comprising at least one carbon atom, and that may contain at least one heteroatom,
• A, which may be identical or different, forms an anchoring moiety to the substrate, and is chosen from the group comprising thiols, thioethers, thioesters, sulphides, thioamides, silanols, silane halides, hydroxyls, phosphates, protected or non-protected phosphonic acids, protected or non-protected phosphonates, amines, ammoniums, nitrogenated heterocycles, carboxylic acids, anhydrides, catechol,
• L, which may be identical or different, is a halogenated C1-C20 carbon moiety,
• R4, which may be identical or different, is H, CH3, a linear or branched, saturated or unsaturated hydrocarbon chain comprising at least 2 carbon atoms, and that may contain at least one heteroatom.
