We have used small-angle neutron scattering to characterize the polymer conformations of four nonionic water soluble polymers: poly~ethylene oxide!, poly~N-vinyl-2-pyrollidone!, poly~N-vinyl-2-caprolactam!, and an N-methyl, N-vinylacetamide/N-vinyl-2-caprolactam copolymer. The last three of these are able to kinetically suppress hydrate crystallization, and their inhibitor activity ranges from ...

Because of availability, as well as economical and environmental considerations, natural gas is projected to be the premium fuel of the 21st century. Natural gas production involves risk of the shut down of onshore and offshore operations because of blockage from hydrates formed from coproduced water and hydrate-forming species in natural gas. Industry practice has been usage of thermodynamic i...
