N. Hurduc et al., LIQUID-CRYSTALLINE POLYMERS - I - CONFORMATIONAL STUDIES OF SOME POLYETHERS AND COPOLYETHERS, Revue Roumaine de Chimie, 42(8), 1997, pp. 709-714
This paper presents conformational studies for some liquid crystalline
polyethers and copolyethers based on 3,3-bis(chloromethyl)oxetane, 4,
4'-dihydroxy-azobenzene, 4,4'-dihydroxy-diphenyl and bisphenol-A. Thes
e studies try to explain the disappearance of liquid crystalline mesop
hase of some copolymers when two different bisphenols are used in the
reaction.
