Patent

CA 2555054

The invention relates to the use of a polymer comprising salts of amine~functional groups and/or salts of phosphine-functional groups bound (pendant) to the backbone of the polymer, said salts comprising as counter-ion the anionic residue of an acid having an aliphatic, aromatic, or alkaryl hydrocarbon group comprising at least 5 carbon atoms in antifouling compositions. The invention further relates to antifouling compositions comprising such a polymer.

L'invention concerne l'utilisation d'un polymère comprenant des sels de groupes à fonction amine et/ou des sels de groupes à fonction phosphine liés (suspendus) au squelette du polymère. Ces sels comprennent, en tant que contre-ion, le résidu anionique d'un acide comprenant un groupe hydrocarbure aliphatique, aromatique ou alkaryle comprenant au moins 5 atomes de carbone dans des compositions antisalissure. L'invention concerne également des compositions antisalissure comprenant ce polymère.
