摘要：

Liquid-crystalline polymers with mesogenic groups in the main chain and side chains as well as their networks are studied by the dynamic mechanical method. The homopolymers are compared with chiral copolymers of a similar chemical structure. Mechanical relaxation transitions are correlated with transitions observed by differential scanning calorimetry. In the nematic phase a flow-thinning effect has been observed both for uncrosslinked polymers and for crosslinked systems. A possible molecular interpretation of the observed mechanical behaviour is discussed.
