Title

SYNTHESIS OF MAIN CHAIN LIQUID CRYSTALLINE POLYESTERS BASED ON MESOGENIC MONOMERS WITH CONTROLLED TRANSITION TEMPERATURES

Pages

  121-130

Abstract

 The structure-property relationships in segmented-chain liquid crystalline POLYESTERs based upon diphenols and aliphatic dibasic acid chloride was studied by differential scanning calorimetry (DSC) and polarizing optical microscopy (POM). Two MESOGENIC MONOMERS were synthesized by direct ESTERIFICATION of hydroquinone with p-hydroxybenzoic acid in a convenient method. The well-characterized MESOGENIC MONOMERS incorporated into segmented liquid crystalline POLYESTERs with short linear chain and COOH-end groups. The structure of the monomers and the polymers was studied by FTIR,1 H NMR, MS. The temperature of transition between the phases and, as a consequence, the range of mesomorphism is highly dependent upon the molecular weight of the POLYESTERs and the length of the MESOGENIC MONOMERS.
