| Popis: | A capillary column for gas chromatography was prepared using microspherical particles of hypercrosslinked polystyrene. The hypercrosslinked stationary phase approximates the stationary phases based on the poly(trimethylsilylpropyne) membrane polymer according to the sorption enthalpy of light hydrocarbons, but proved markedly inferior to the latter phases according to the kinetic efficiency. Direct synthesis in a column with a hypercrosslinked stationary phase based on hypercrosslinked polystyrene led to the formation of a nonporous polymer, which had no separating ability with respect to light hydrocarbons. |
