METHACRYLIC COPOLYMERS PREPARED BY THE ULTRASOUND METHOD - CHIRAL HPLC AND GC APPLICATIONS

Methacrylic macroporous copolymers were synthesized for HPLC and GC ap plications. Preparation of polymers for chiral ligand exchange chromat ography has been studied. Comparisons with previous chromatographic ap plications have been done. Results show that improvement of physical c haracteristics of polymers (specific area and pore volume) improves th e separation of enantiomers. Very polar stationary phases for GC were prepared for separation of freons. The chromatographic results proved that polar phases are very selective for this kind of compounds. Separ ation can be accomplished even though retention times are short.
