The present invention relates to a fluorine-containing graft copolymer and its manufacturing method. In particular, the fluorine-containing graft copolymer synthesized by copolymerization of copolymerizable perfluoroalkyl compound as a main chain and macromonomer having copolymerizable vinyl group at one end as branched chains, respectively. Thus the graft copolymer has the remarkable affinity to the substrates designed for the surface modification and superior performance than random copolymers, when it is employed as various types of surface modifiers of fluorine-containing compounds (e.g., water and oil repellent, soil release agents, mold-releasing agents, etc.).
La présente invention concerne un copolymère greffé fluoré et son procédé de fabrication. En l'occurrence, on synthétise le copolymère greffé fluoré par copolymérisation d'un composé dont la chaîne principale est un perfluoroalkyle copolymérisable, et dont les ramifications de chaîne sont un macromonomère portant sur l'une de ses extrémités un groupe vinyle copolymérisable. Ce copolymère greffé fait ainsi preuve, d'une part d'une affinité remarquable pour les substrats conçus pour la modification de surface, et d'autre part d'un rendement supérieur à celui de n'importe quels autres copolymères, pour ses diverses formes d'utilisation en tant que modificateur de surface de composé fluoré, par exemple, comme hydrofuges ou oléophobes, comme agent de prélavage ou comme agent de démoulage.
