POLYMERS FOR USE AS HYDRATE INHIBITORS

摘要

The instant invention relates to novel copolymers of N-vinyl amides and acrylamides and N-allyl amides and acrylamides. The polymers are used for inhibiting the formation of clathrate hydrates in a fluid having hydrate forming constituents. The polymers can also be used in treating a petroleum fluid stream such as natural gas conveyed in a pipe to inhibit the formation of a hydrate restriction in the pipe.
