英文摘要	In this paper, a novel block copolymer poly (N-vinyl caprolactam)-co-acrylamide) (PVCap-co-AM) was made from N-vinyl caprolactam (NVCap) with acrylamide (AM) by living radical copolymerization. The kinetic inhibitory performance of PVCap-co-AM on CH4 hydrate formation was firstly investigated and compared with PVP and PVCap. The results indicated that higher-cloud-point PVCap-co-AM behaved better than PVCap under the same conditions. Powder X-ray diffraction (PXRD) spectroscopy and Raman spectroscopy showed structure I hydrate was formed with and without KHIs. However, compared to pure water, the presence of KHIs reduced the ratio of large to small cage occupancy by CH4. The stronger inhibition activity, the value became lower. CryoSEM images illustrated the morphology of CH4 hydrate crystals formed significantly varied by KHIs, which could be helpful for pipeline fluids safe transportation.
