VINYLLACTAM COPOLYMERS USED AS GAS HYDRATE INHIBITORS
摘要
The invention relates to the use of copolymers as gas hydrate inhibitors, whereby these copolymers are synthesized from: 40 to 99.5 % by weight of at least one ethylenically unsaturated cyclic lactam A; 0.5 to 60 % by weight of monomers B having a solubility in water of less than 10 parts by weight of monomers in 100 parts by weight of water, and; 0 to 50 % by weight of other monomers C.
