摘要

The synthesis and characterization of a variety of mesomorphic (Iiquid-crystalline) sidechain polysiloxane (MEPSIL) solvents, said to be useful as gas chromatographic statlonary phases, are descrlbed and discussed. The synthetlc scheme Is based upon the hydrosilatlon reaction that occurs when 4-(aliyioxy) benzoyl esters are contacted with poiy (methy1- siloxane) in the presence of a dicyciopentadienyiplatinum (II) catalyst, while product ...
