Abstract

The present invention relates to a grafted copolymer bearing grafts of formula (I):—O—PM1—(PM2)—T  (I)in which:PM1 represents a polymer block obtained by (co)polymerization of at least one monomer M1 via a radical route; andPM2, which is optionally present, represents a polymer block obtained by (co)polymerization of at least one monomer M2 via a radical route; andT represents the residue of a stable radical T•.
