摘要：

The present paper studies the influence of the chain's chemical structure on the thermal behavior of some polyethers. The investigated polymers were synthesised by phase transfer catalysis using 3,3-bis(chloromethyl)oxetane and various bisphenols as monomers. The polymers were characterized by H-1-NMR spectroscopy, DSC technique and optical microscopy in polarized light. Theoretical conformational studies were also performed. Among the studied polymers, only those containing 4,4'-dihydroxyazobenzene and 4,4'-dihydroxybenzophenone can present liquid crystalline behavior. The copolyethers containing the 4,4'-dihydroxydiphenyl do not present liquid crystalline behavior.
