Abstract
Side chain type liquid crystalline copolyesters containing alternative polar and non-polar mesogenic end groups were synthesized. Furthermore, side chain type liquid crystalline copolyester with a random sequence of the polar and non-polar mesogenic end groups was also prepared. The induced smectic phase was exhibited for the copolyester containing alternate polar and non-polar mesogenic end groups in the side chain. The mesomorphic temperature range was influenced by the sequence of the mesogen with the polar or non-polar group. Further, the thermal properties of the mixture of copolyesters with polar and non-polar end groups were investigated. A mixture of 10–50 mol% of copolyesters with polar end groups exhibited an induced smectic phase.
