摘要：
Dielectric relaxation measurements have been carried out in the frequency range from 1 Hz to 100 kHz on copolymers with different molar ratios of two liquid crystalline, parts. Two dielectric relaxation ranges were detected which are related to the two respective parts. The copolymers show an increasing molecular mobility with respect to the homopolymers. The results are discussed in relation to the phase diagram and to dielectric data on low molecular liquid crystals.
