Abstract
Abstract Organo metallic polymer compositions useful as constituents of anti-fouling paints for marine structures, comprising a main chain consisting of a chlorinated conjugated diene polymer 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.
