Abstract

L'invention concerne une micelle à écorce réticulée hautement stable ayant une sensibilité au stimulus à l'intérieur de la micelle, l'environnement interne changeant en réponse à des stimuli externes. L'invention concerne particulièrement une micelle à écorce réticulée contenant un copolymère à blocs obtenu par copolymérisation à blocs d'un monomère alcényl éther sensible au stimulus, d'un monomère alcényl éther soluble, qui est soluble dans un solvant devant être utilisé, et d'un monomère alcényl éther ayant un groupe pouvant être réticulé, puis par photréticulation de la partie d'écorce.
