The invention relates to a polymer comprising quaternary ammonium and/or quaternary phosphonium groups bound to the backbone of the polymer, said quaternary ammonium groups and/or quaternary phosphonium groups being neutralised by counter-ions, wherein the counter-ions consist of the anionic residue of an acid having an aliphatic, aromatic, or alkaryl hydrocarbon group comprising 6 or more carbon atoms. The invention further relates to the preparation of this polymer, its use in anti-fouling compositions, and to anti- fouling compositions comprising the polymer.
L'invention concerne un polymère comprenant des groupes d'ammonium quaternaires et/ou de phosphonium quaternaire neutralisé par des contre-ions. Ces contre-ions consiste en des restes anioniques d'un acide possédant un groupe d'hydrocarbures aliphatiques, aromatiques ou alkaryles qui comprend au moins 6 atomes de carbone. L'invention concerne également la préparation de ce polymère, son utilisation dans des compositions antisalissures et des compositions antisalissures contenant ce polymère.
