ResumoA bstract : Growth and inhibition of single crystals of ethylene oxide clathrate hydrate provide experimental accessibility to similar phenomena in methane clathrate hydrates. Ethylene oxide hydrate single crystals were grown in a simple experimental setup. The crystals grew from the subcooled melt as rhombic dodecahedra, macroscopically exhibiting {110} as the slowest growing faces. The addition of minute amounts of poly(N‐vinylcaprolactam) (PVCap) or a random terpolymer of PVCap, poly(N‐vinylpyrrolidone), and dimethylaminoethylmethacrylate (VC‐713) caused small‐scale branching of crystals, but with a seemingly uniform crystal orientation. A few tenths of a weight percent of these additives caused complete crystal growth inhibition at several degrees of subcooling.
