Organo metallic polymer compositions useful as constituents of anti-fouling paints for marine structures, comprising a main chain consisting of a chlorinated polymer of a conjugated diene monomer such, for example, as a chlorinated polybutadiene of high 1, 2 units content, and at least one grafted chain formed at least partly of recurrent units having a pendant organotin group or tin salt function, wherein the grafted chains also contain recurrent units derived from at least one hydrophilic non-metallic unsaturated organic monomer.

Organometallic polymer compositions useful as constituents of

A method of protecting submerged articles from fouling by applying a surface pellicle of a coating substance containing an anti-fouling amount of an organo metallic composition comprising a main chain consisting of a chlorinated polymer of a conjugated diene monomer such, for example, as a chlorinated polybutadiene of high 1, 2 units content, and at least one grafted chain formed at least partly of recurrent units having a pendant organotin group or tin salt function.
