Abstract

The general gas chromatographic retention behavior of cyclic methylsiloxanes partially substituted with phenyl or 2‐cyanoethyl groups has been systematically studied, with pyrolysis‐gas chromatography being utilized to form the cyclic siloxanes from the corresponding polysiloxanes at a temperature of 600°C. Kovats retention indices (KI) were determined for the cyclic siloxanes by use of the retention data of the pyrolyzates from polyethylene as standards. The effect of phenyl and 2‐cyanoethyl substituents in the cyclic siloxanes on retention behavior has also been considered.
