8. The comb copolymer A2 as claimed in claim 5, in which the oligomers O1 are present in the copolymer A2 in the form of repeat units corresponding to one or more monomers M6 of general formula (IX):, in which:
Q1 is chosen from the group consisting of —H, —CH3 and —CH2—CH3;
Q2 is chosen from the group consisting of -Q′, −O-Q′, —C(O)—O-Q′, −O—C(O)-Q′, —S—(CH2)2—C(O)—O-Q′, —S-Q′, —N(H)—C(O)-Q′ and —C(O)—N(H)-Q′ group, with Q′ is a polyolefin,
n represents an integer chosen from 0 and 1,
A represents a divalent group chosen from the group consisting of -A1-, —O-(-A2-O-)n′-A1-, —C(O)—O—(-A2-O-)n′-A1-, −O-C(O)-(-A2-O-)n′-A1-, —S—(-A2-O-)n′-A1-, —N(H)—C(O)—(-A2-O-)n′-A1 and —C(O)—N(H)-(-A2-O-)n′-A1- with:
A1 is a divalent group chosen from the group consisting of a C1-C30 alkyl, a C6-C30 aryl and a C6-C30 aralkyl,
A2 is a divalent group chosen from C2-C4 alkyls,
n′ is an integer, n′ represents 0 or 1.
