A method of inhibiting hydrates in a fluid comprising water and gas comprising adding to the fluid an effective hydrate-inhibiting amount of a composition comprising one or more homo- or co-polymers of N-alkyl(alkyl)acrylamide synthesized by polymerizing one or more N-alkyl(alkyl)acrylamide monomers in a solvent comprising a glycol ether of formula CH&#x2014;(CH)&#x2014;(O&#x2014;CH&#x2014;CH)&#x2014;OH where m is an integer of 0-1, and n is an integer &#x2265;1.

Method of controlling gas hydrates in fluid systems

A method of inhibiting hydrates in a fluid comprising water and gas comprising adding to the fluid an effective hydrate-inhibiting amount of a composition comprising one or more copolymers of N-alkyl (alkyl)acrylamide monomers and one or more cationic monomers selected from acid and alkyl chloride quaternary salts of N,N-dialkylaminoalkyl (meth)acrylates and N,N-dialkylaminoalkyl (meth)acrylamides.
