Abstract:
A block copolymer including: at least one block A of following formula (I): in which p is an integer ranging from 2 to 100, R1′ is selected from hydrogen and the methyl group, R2′ is chosen from C1 to C34 hydrocarbon-based chains, at least one block B of following formula (II): in which n is an integer ranging from 2 to 40, R1 is chosen from hydrogen and the methyl group, Z is chosen from the oxygen atom and the group —NR′— with R′ being chosen from a hydrogen atom and C1 to C12 hydrocarbon-based chains, G is a C1 to C34 hydrocarbon-based chain substituted by at least one quaternary ammonium group and optionally one or more hydroxyl groups. Also, the use of such a block copolymer as detergent additive in an internal combustion engine liquid fuel.

Claim (Index 9):
The block copolymer as claimed in  claim 7 , in which block B of formula (III), (IV), (V) or (VI) is derived from a monomer (m b ) obtained by the reaction:\n of a tertiary amine of formula NR 3 R 4 R 5  or R 6 N\u2550R 7  in which R 3 , R 4 , R 5 , R 6  and R 7  are as defined in  claim 7 , and of a (meth)acrylate or (meth)acrylamide intermediate monomer (m i ) of formula (VII) below: in which Z is chosen from an oxygen atom and a group \u2014NR\u2032\u2014 with R\u2032 being chosen from a hydrogen atom and C 1  to C 12  hydrocarbon-based chains, R 1  is chosen from hydrogen and a methyl group, R 8  is chosen from C 1  to C 32  hydrocarbon-based chains, and R 9  is chosen from hydrogen and C 1  to C 6  alkyl groups.
