The dielectric loss spectrum of a side chain liquid crystal polymer (SCLCP) has been measured from 10 Hz to 100 kHz in the smectic phase. Three liquid crystalline siloxane polymers are examined, a homopolymer and two random copolymers, all of which contain a chiral smectic mesogen and an eleven-methylene spacer in the side chain. Two dielectric relaxations have been observed, the high-frequency α and low-frequency δ processes. The effect of the copolymer morphology in these SCLCPs is to increase the dielectric relaxation strength of the δ process relative to the α process and to cause increased overlap between the two peaks. These two observations suggest that the copolymer structure aids large scale reorientations in the δ process because of increased cooperativity with the backbone.
