摘要:
In the analysis of spectroscopic data from liquid crystals consisting of either small molecules or polymer chains, it is essential that account be taken of some particular features due to the oriented nature of the phases investigated. For liquid crystal polymers some specific additional problems arise, such as the difficulties in orienting main-chain liquid crystal polymers, the occurrence of the glass-liquid transition and secondary transitions. These questions are first discussed, then the studies performed using2H and13C N.M.R., E.S.R. and dielectric relaxation on both side-chain and main-chain liquid crystal polymers are presented.
