Graft copolymers based on a polyamide which was reacted with maleic anhydride and which has at least one vinylically unsaturated side chain are proposed, this grafted side chain containing at least one representative selected from a) N-vinylcaprolactam and/or b) N--vinylpyrrolidone. Inter alia, natural but also synthetic polyamides are provided as preferred polyamide components. Such graft copolymers, but also generally polyamide- based graft copolymers composed of at least one side chain containing ethylenically unsaturated compounds, are in general suitable in construction chemistry applications but also in the development, exploitation and completion of underground mineral oil and natural gas deposits and in deep wells and moreover in the extraction and the transport of oil or gas and here in particular as a gas hydrate inhibitor.

L'invention concerne des copolymères greffés à base d'un polyamide qui a réagi avec un anhydride d'acide maléique, présentant au moins une chaîne latérale vinyliquement insaturée, cette chaîne latérale greffée contenant au moins un composé choisi entre a) N-Vinylcaprolactame et/ou b)-Vinylpyrrolidone. Les composants de polyamide préférés sont notamment des polyamides naturels mais également des polyamides synthétiques. Les copolymères greffés de ce type, mais également de manière générale les copolymères greffés à base de polyamide comprenant au moins une chaîne latérale contenant des liaisons éthyléniquement insaturées, conviennent de manière générale pour des applications de chimie du bâtiment, mais également pour l'aménagement, l'exploitation, et la finition des dépôts de pétrole et de gaz naturel souterrains, ainsi que pour des forages profonds, de même que pour l'extraction et le transport de pétrole ou de gaz, en particulier en tant qu'inhibiteurs d'hydrates de gaz.
