Av. Tenkovtsev et Ay. Bilibin, SPECTRAL CHANGES IN THE ANISOTROPIC PHASE OF LIQUID-CRYSTALLINE POLYMERS WITH BIPHENYLENE FRAGMENTS, Vysokomolekularnye soedinenia. Seria A, 40(6), 1998, pp. 1048-1050
The effect of liquid-crystalline ordering on the spectral properties o
f polyesters containing biphenylene groups in the main chain was inves
tigated. Changes of the UV reflection spectra observed in the anisotro
pic state of polymers based on 3,3'- and 4,4'-biphenyldiols were attri
buted to the changes in conformation of the mesogenic group.
