Abstract
The present invention relates to a method making it possible to ensure a gradual release of polymer chains within a liquid medium, said method comprising bringing said 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 said polymer chains within said 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.
Claims19
A method for the gradual release of polymer chains within a liquid release medium (LRM), said method comprising a step (S) where said medium (LRM) is brought into contact with solid objects, formed by polymer chains soluble in the medium (LRM) and carrying hydrophobic side groups ensuring hydrophobic/hydrophobic physical crosslinking between said polymer chains within said solid objects.
