Abstract: Polybutadiene oligomer was encapsulated on specially presilanized silica particles by γ-radiation crosslinking and by addition of a definite amount of tripropylene glycol diacrylate or ethylene dimethacrylate as enhancement reagent. The effects of kind and content of the enhancement reagent and radiation dose on the crosslinking products are discussed. The elemental analysis results, scanning electron micrograph and diffuse reflectance infrared spectra were proof that the preparing process is successful. Such material is easy to pack and yields high efficiencies. Its supper performance for the separation mixtures of aromatic hydrocarbons, alkyl benzenes and amino-containing compounds are demonstrated by practical examples.

Key words: Polybutadiene, Polymer encapsulated packing, Crosslinking by γ-radiation, Chromatographic properties
