Abstract

L'invention concerne un procédé de préparation d'un copolymère séquencé comprenant la polymérisation dans un milieu aqueux dans des conditions de polymérisation par transfert de chaîne par addition-fragmentation réversible de a) une première composition monomère comprenant de l'acide méthacrylique en une quantité de 0,0 à 40,0 % en mole et au moins 50,0 % en mole d'un ou plusieurs monomères polymérisables éthyléniquement insaturés présentant une solubilité dans l'eau supérieure à 500 g/l à 20 °C, choisis parmi les monomères présentant des groupes éther et les monomères présentant des groupes hydroxyle, afin de préparer un premier bloc polymère et b) une deuxième composition monomère comprenant au moins 60,0 % en poids d'un ou de plusieurs monomères polymérisables éthyléniquement insaturés présentant une solubilité dans l'eau inférieure à 50 g/l à 20 °C afin de préparer un deuxième bloc polymère.
