Title (EN) COPOLYMER BINDER
(FR) LIANT COPOLYMÉRIQUE
Abstract:
(EN) The present invention relates to a copolymer comprising a monomer A with a molar ratio a varying between around 0.01 and around 0.20, a monomer B with a molar ratio b varying between around 0.2 and around 0.4, and a monomer C with a molar ratio c varying between around 0.50 and around 0.70, the monomer A being a hydrophilic monomer comprising a pendant chain of poly(ethylene oxide) (POE) with low molar weight, the monomer B being a hydrophobic monomer with a glass transition temperature (Tg) of around -30°C or less, the monomer C being a monomer that is more hydrophobic than the monomer B and having a glass transition temperature (Tg) of around 80°C or more, said monomers being organised in a hydrophilic segment, a hydrophobic segment and an intermediate segment located between the hydrophilic segment and the hydrophobic segment.
(FR) La présente invention concerne donc un copolymère comprenant un monomère A dans un ratio molaire a variant entre environ 0.01 et environ 0.20, un monomère B dans un ratio molaire b variant entre environ 0.2 et environ 0.4 et un monomère C dans un ratio molaire c variant entre environ 0.50 et environ 0.70, le monomère A étant un monomère hydrophile comprenant une chaîne pendante de poly(oxyde d'éthylène) (POE) de faible masse molaire, le monomère B étant un monomère hydrophobe ayant une température de transition vitreuse (Tg) d'environ -30°C ou moins, le monomère C étant un monomère plus hydrophobe que le monomère B et ayant une température de transition vitreuse (Tg) d'environ 80°C ou plus, lesdits monomères étant organisés en un segment hydrophile, un segment hydrophobe et un segment intermédiaire situé entre le segment hydrophile et le segment hydrophobe.
