摘要： Polymers are provided for use in inhibiting gas hydrate formation and/or corrosion in hydrocarbon-containing fluids. The polymer comprises repeat units derived from a first monomer comprising N-[3-(dibutylamino)propyl]methacrylamide (DBAPAMA) or an alkyl, acetyl, acryloyl or benzyl quaternary salt thereof, N-[3-(diisobutyl)propyl]methacrylamide or an alkyl, acetyl, acryloyl or benzyl quaternary salt thereof, N-[3-(diisopentyl)propyl]methacrylamide or an alkyl, acetyl, acryloyl or benzyl quaternary salt thereof, or a combination thereof; and repeat units derived from a second monomer comprising acrylamide, N-alkylacrylamide, N-alkyl (alkyl)acrylamide, ((dialkylamino)alkyl)acrylamide or an alkyl or benzyl quaternary salt thereof, ((dialkylamino)alkyl)alkylacrylamide or an alkyl or benzyl quaternary salt thereof, acrylic acid, alkyl acrylate, N,N-(dialkylamino)alkyl acrylate or an alkyl or benzyl quaternary salt thereof, N,N-(dialkylamino)alkyl (alkyl)acrylate or an alkyl or benzyl quaternary salt thereof, hydroxyalkyl acrylate, hydroxyalkyl (alkyl)acrylate, acrylamido alkyl sulfonic acid or a salt thereof, a diallyl dialkyl quaternary ammonium salt, or a combination thereof. The second monomer does not comprise the first monomer.

摘要： The present invention generally relates to methods and hydrate inhibitor compositions for inhibiting the formation of hydrates in a fluid comprising gas and water. More specifically, the method comprises contacting a hydrate inhibitor composition to a fluid. The hydrate inhibitor composition comprises a nonpolar solvent; a polar solvent; and a polymer, an oligomer, a dendrimer, or an acid or salt thereof.
