Abstract

L'invention propose des copolymères séquencés comprenant des liaisons polyester. Ces copolymères sont obtenus par réaction de précurseurs de formation de polyester, d'agents RAFT et de monomères polymérisables par voie radicalaire. L'invention propose en outre des compositions comprenant les copolymères séquencés et leurs applications dans divers domaines industriels. L'invention propose en outre un procédé de réduction de la taille de particules d'un principe actif par obtention d'une composition qui comprend des particules colloïdales des copolymères séquencés et du principe actif et par soumission de la composition à une opération de réduction de taille appropriée. Chaque a, b et R11 sont décrits dans la présente invention.
