Claim 8:
9. The comb copolymer A2 as claimed in claim 1, comprising at least repeat units corresponding to monomers M4 of formula (IV):, in which:
t is an integer equal to 0 or 1;
u is an integer equal to 0 or 1;
M and R8 are divalent linking groups, which are identical or different, chosen from the group consisting of a C6-C18 aryl, a C7-C24 aralkyl and a C2-C24 alkyl;
X is a functional group chosen from the group consisting of —O—C(O)—, —C(O)—O—, —C(O)—N(H)—, —N(H)—C(O)—, —S—, —N(H)—, —N(R′4)— and −O—, with R′4 a hydrocarbon chain comprising from 1 to 15 carbon atoms;
R9 is chosen from the group consisting of —H, —CH3 and —CH2—CH3;
R10 and R11, which are identical or different, represent a group chosen from the group consisting of a hydrogen atom and a hydrocarbon group comprising from 1 to 30 carbon atoms, optionally substituted by one or more groups chosen from: a hydroxyl or an —OJ or —C(O)—O-J group, with J a hydrocarbon group comprising from 1 to 24 carbon atoms.
