Summary
A series of polymer-encapsulated packing materials for reversed phase high-performance liquid chromatography was prepared by radical polymerization of ethylstyrene and divinylbenzene with vinyl-modified silica in solution. Some characteristics such as polymer structure, swelling propensity, residual silanols, column efficiency and retention properties were evaluated. Such material is easy to pack and yields high column efficiencies. Its superior performance for the separation of mixtures of aromatic hydrocarbons, amino- and hydroxyl group containing compounds are demonstrated by several examples.
