Abstract: A substrate comprising a surface at least a portion of which is covered with an epilame agent, comprising at least one compound in the form of a copolymer comprising units M and units N, associated by covalent bonds via their main chains, where
M is




N is




where R1 and R2, which may be identical or different, are H, a C1-C10 alkyl group, a C2-C10 alkenyl group; X and Y, which may be identical or different, are spacer arms consisting of a heteroatom or a linear or branched hydrocarbon chain containing at least one heteroatom and comprising at least one carbon atom; A, which may be identical or different, forms an anchoring group to the substrate; L, which may be identical or different, is a halogenated ether group according to formula (I)




where Q is a halogen atom; P, which may be identical or different, is a C1-C10 alkyl group or a C2-C10 alkenyl group comprising at least one halogen atom and being linear or branched; p is chosen between 1 and 4; and n is chosen between 1 and 20.
