Abstract:
The use of a copolymer as a detergent additive in an internal combustion engine liquid fuel. The copolymer obtained by copolymerization of at least: an alkyl acrylate or alkyl methacrylate monomer ma and a styrenic monomer mb chosen from styrenics derivatives, the aromatic ring of which is substituted by at least one group R or at least one linear or branched C 1  to C 12  hydrocarbon-based chain substituted by at least one group R being chosen from: the hydroxyl group, a group —OR′, a group —(OC y H 2y O) f —H, a group —(OC y H 2y O) f —R′, a group —O—(CO)—R′, and a group —(CO)—OR′, where y is an integer ranging from 2 to 8, f is an integer ranging from 1 to 10, and R′ is chosen from C 1  to C 24  alkyl chains. Also, a process for maintaining the cleanliness of and/or for cleaning at least one of the internal parts of an internal combustion engine.

Claim (Index 26):
A method comprising supplementing a liquid fuel for internal combustion engines with a copolymer detergent additive, said copolymer being obtained by copolymerization of at least:\n an alkyl acrylate or alkyl methacrylate monomer (m a ) and a styrenyl monomer (m b ) chosen from styrene derivatives wherein the aromatic nucleus is substituted with at least the group R or with at least one linear or branched C 1  to C 12  hydrocarbon-based chain, substituted with at least one group R, said group R being chosen from: a hydroxyl group, a group \u2014OR\u2032,\n a group \u2014(OC y H 2y O) f \u2014H, \n a group \u2014(OC y H 2y O) f \u2014R\u2032, \n a group \u2014O\u2014(CO)\u2014R\u2032, and a group \u2014(CO)\u2014OR\u2032, y is an integer ranging from 2 to 8, f is an integer ranging from 1 to 10 and R\u2032 is chosen from C 1  to C 24  alkyl chains.
