Investigation into the inhibition of methane hydrate formation in the presence of hydroxy-terminated poly(N-vinylcaprolactam)
Hydroxy-terminated poly(N-vinylcaprolactam) (PVCap-OH) with a narrow molecular weight distribution (PDI = 1.06) has been synthesized. PVCap-OH gave a cloud point of 51.7 degrees C, 10.6 degrees C higher than that of the synthesized PVCap (41.1 degrees C). Its KHI performance was tested using a high-...
