To understand better the antagonistic behaviour of the backbone in comparison with the mesogenisity of the pendant side groups
in side-chain liquid crystal polymers series of measurements using mechanical spectroscopy as well as DSC were carried out
on two disubstituted polynorbornene derivatives.
In order to clarify the specific arrangement of chains, the influence of thermal history on the smectic phase stabilisation
were studied. By quenching samples from different temperatures, it was possible to obtain the systems which were either in
the glassy liquid-crystalline (LC) state or in the glassy isotropic amorphous state. The samples prepared in such ways were
used to study the influence of the LC structure on the mobility of chains in amorphous regions. The quality model of the supermolecular
structure of the LC polymers is proposed.
