COMPOSITION FOR PREVENTING MARINE GROWTH, CONTAINING POLYMER WITH SALT GROUPS Russian patent published in 2009 - IPC C09D5/16 

FIELD: chemistry.

SUBSTANCE: antifouling coating composition contains rosin as binder and a polymer, which contains a salt group, obtained using a method which involves stages for reacting acid, containing an aliphatic, aromatic or alkylaryl hydrocarbon group, containing at least 5 with a monomer, which contains amino- or phosphine groups in which: Y is O or NH, Z is N or P, R¹ is a hydrogen atom or C₁-C₄ alkyl group, R² is a divalent hydrocarbon group C₂-C₁₂, R³ and R⁴ are independently a hydrogen atom or C₁-C₆ alkyl group or an optionally substituted phenyl group, obtaining a monomer which contains an amino group salt and/or phosphine group salt, where the said salt contains anionic acid residue as a counterion, with an aliphatic, aromatic or alkylaryl hydrocarbon group, which contains at least 5 carbon atoms, and polymerisation of at least one type of the said monomer, containing salt.

EFFECT: antifouling coating composition is used for protecting underwater manmade structures, such as ship hulls, buoys, drilling platforms, oil rigs and pipes.
