Abstract

In this work, we report the study of properties of capillary columns with a porous layer of the functionalized polymer prepared via oxidation of poly-(1-trimethylsilyl-1-propyne) (PTMSP) by nitrous oxide. It was shown that the double CC bonds of polymer reacted with nitrous oxide with formation of ketone, carbonyl and hydroxyl groups. The increase in number of those groups in polymer changed a polarity of PTMSP. The change in polarity of polymer led to the selectivity of separations, including oxygen-containing substances. The polarity values were calculated for the prepared columns. It was shown that the total polarity according to McReynolds (ΔI) was lower than that for known porous polymers. The examples of separations of aliphatic and aromatic hydrocarbons, oxygen- and halogen-containing substances were presented.
