Beschreibung
Zusammenfassung:	Provided is a composition comprising at least one polymer, the repeat unit of which comprises at least one amide functional group, at least one polyetheramine with a weight-average molecular weight (Mw) of greater than 100 g.mo1−1 and exhibiting at least two secondary and/or tertiary amine functional groups, and optionally, but preferably, at least one organic solvent. Also provided is method of using of the composition for delaying, indeed even preventing, the formation of gas hydrates, in particular in a process for extracting oil and/or gas and/or condensates, and also to the process for delaying, indeed even preventing, the formation and/or the agglomeration of gas hydrates, employing a composition as defined above.
