Macroporous polymeric sorbents for chromatography, especially gas chromatography of organic compounds

The invention relates to macroporous polymeric sorbents prepared by ternary copolymerization of polar monomers, namely hydroxyalkyl acrylates and methacrylates (hydroxyalkyl C1-6), in the amount of 1 - 70 wt.%, with 30 - 90 wt.% of nonpolar comonomers, namely alkyl acrylates and methacrylates (alkyl C1-18), and 20 - 80 wt.% of crosslinking agents, namely alkylene diacrylates and dimethacrylates (alkylene C1-6). The sorbents were prepared by the suspension copolymerization in the presence of inert organic solvents and surfactants in the single step without further chemical modification and their polarity was controlled in a broad region. They are especially suitable for gas-chromatographic separation of organic compounds, as hydrocarbons, alcohols, organic acids and nitrogen-containing heterocyclic compounds. Their preparation in one step is more simple and economical than modification of the polymeric matrix by polymeranalogous reactions which has been used for this purpose until present time.
