Abstract
An in situ method of bonding monolithic rods clad in poly-ether-ether-ketone (PEEK) based on polyhydrogenosiloxane is described. The hydrogenosiloxanes provide good solubility for the substances used in the silanization reaction in aromatic hydrocarbon solvents (non-aggressive to PEEK). The reaction of the Si-H bond with silanol groups produces hydrogen as a non-aggressive byproduct to the environment. This hydrogenosiloxane method is illustrated in the synthesis of monomeric and polymeric acceptor-bonded, monolithic phases. The use of these new bonded monolithic rods for the separation of PAHs in normal phase LC is described.
