Abstract
Provided is a method making it possible to ensure a gradual release of polymer chains within a liquid medium, the method comprising bringing the liquid medium into contact with specific solid objects formed by polymer chains soluble in the medium and carrying hydrophobic side groups ensuring physical crosslinking between the polymer chains within the solid objects. The released chains may in particular be used as inhibitors of the formation of inorganic or organic deposits (scale inhibitors) within a liquid medium, typically in the field of oil extraction.
