4'-oxyazoxybenzene ester) (PAB)series with different number of methylene group in flexible unit have been synthesized.The odd-even effect of phase transition temperature has been obviously observed by DSC measurement. The nature and the main factor of odd-even effect have been investigated by dynamic FTIR. The effect of symmetric structure of mesogenic unit in main chain on the phase transition temperature of liquid crystal polymer has been discussed by comparing with poly (2
