Abstract
Stationary phases, useful for reversed-phase liquid chromatography, comprise polybutadiene-coated inorganic substrates having enhanced hydrophobicity due to attached alkyl groups, e.g. 2-30 carbon alkyl groups such as an octadecene group, and a low level of carbon-oxygen bonding in the polymer coating, e.g. less than 1 percent of the carbon in the polymer coating is bonded to oxygen.
