Abstract
The present paper studies the influence of the chain's chemical struct ure on the thermal behavior of some polyethers. The investigated polym ers were synthesised by phase transfer catalysis using 3,3-bis(chlorom ethyl)oxetane and various bisphenols as monomers. The polymers were ch aracterized by H-1-NMR spectroscopy, DSC technique and optical microsc opy in polarized light. Theoretical conformational studies were also p erformed. Among the studied polymers, only those containing 4,4'-dihyd roxyazobenzene and 4,4'-dihydroxybenzophenone can present liquid cryst alline behavior. The copolyethers containing the 4,4'-dihydroxydipheny l do not present liquid crystalline behavior.
