Abstract
Copolyethers based on 3,3-bis(chloromethyl) oxetane and several bisphe nols [4,4'-dihydroxyazobenzene, bisphenol A and 1,1-bis-(4-hydroxyphen yl)ethane] were synthesized. The influence of chain geometry and flexi bility on the possible appearance of liquid crystalline behavior was i nvestigated. Polymer properties were studied using H-1 NMR spectroscop y, DSC, optical microscopy in polarized light and theoretical conforma tional analyses. The optimal mesogen/nonmesogen ratios, correlated wit h the flexibility of the chain and anisotropic behavior was establishe d. (C) 1997 Elsevier Science Ltd.
