The present invention relates to amphiphilic branched copolymers, methods for their preparation, emulsions com-prising such copolymers and their use as emulsifiers. The polymers are responsive by nature, by forming non-covalent bonds be-tween monomer residues upon applying external stimuli. In a preferred embodiment of the copolymer, the copolymer can be used to stabilise emulsions and the emulsion droplets can be reversibly aggregated and de-aggregated.

La présente invention concerne des copolymères ramifiés amphiphiles, leurs procédés de préparation, des émulsions comprenant de tels copolymères et leur utilisation comme émulsifiants. Les polymères sont réactifs par nature, par formation de liaisons non covalentes entre les résidus monomères à lapplication de stimuli externes. Dans un mode de réalisation préféré du copolymère, le copolymère peut être utilisé pour stabiliser des émulsions et les gouttelettes démulsion peuvent sagglomérer et se désagglomérer de façon réversible.
