Abstract
La présente invention concerne une composition comprenant au moins un polymère dont le motif répétitif comprend au moins une fonction amide, au moins une polyétheramine de poids moléculaire en poids (Mw) supérieur à 100, et présentant au moins deux fonctions amines secondaires et/ou tertiaires, et éventuellement, mais préférentiellement, au moins un solvant organique. L'invention concerne également l'utilisation de ladite composition pour retarder, voire empêcher la formation d'hydrates de gaz, notamment dans un procédé d'extraction de pétrole et/ou de gaz et/ou de condensats, ainsi que le procédé pour retarder, voire empêcher la formation et/ou l'agglomération d'hydrates de gaz, mettant en œuvre une composition telle que définie ci-dessus.
