    摘要： A composition for preventing or retarding the formation of gas hydrates during the transport of a fluid comprising water and a hydrocarbon through a conduit. The composition is a copolymer of vinyl caprolactam and vinyl pyridine, and terpolymers thereof, with vinyl pyrrolidone, preferably including 70-97% by weight vinyl caprolactam. Suitably such polymers have a molecular weight in the range of 500 to 2500, and are made in a polymerization solvent, preferably a glycol ether, most preferably, 2-butoxyethanol; and also including a carrier solvent, preferably monoethylene glycol.
