Abstract

A straight, branched or cross-linked polymer, including, per 100 mol %: a) a mole fraction from 75% to 99.95% of monomer units from an N,N-dialkyl acrylamide; b) a mole fraction from 0.05% to 1% of monomer units from a monomer of formula (I): CH2=C(Ri)-C(═O)—O—[(CH2-CH(R2)-O]n-R3 (I); c) optionally a mole fraction higher than 0% to 24% either of monomer units from a monomer including a free strong acid function, partially or totally salified, or of monomer units from a monomer of formula (II): CH2=C(R4)-C(═O)—Y—(CH2)m-N(R5)(R6) (II); d) optionally a mole fraction higher than 0% to 1% of a diethylene or polyethylene cross-linking monomer. Also, a method for treating a surface made of a hydrophobic material, using the polymer, and an aqueous, hydro-organic or organic solution including the polymer for modifying interactions between the species contained the solution and the hydrophobic surface.
