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