摘要

A new side chain crown ether polysiloxane (PSCP-3-15C5) has been prepared and characterized in chromatography. Its chromatographic behavi9ur was compared with that of the other side chain crown ether polysiloxane (PSCP-11-15-C5), which has a longer spacer. The unusual effects caused by the length of the spacer on the polysiloxane backbone are described. An interesting phenomenon, liquid-liquid transition occurring in the measurement of phase transition on PSCP-3-15-C5, is discussed.
