In this research, we estimated the correlation between physical properties andstructures of main and side chains in liquid crystalline polymers which have rigid main chain carrying dense side chain groups. These estimations have been performed in the past only by using liquid crystalline polymers which had soft main chains carrying sparse side chain groups, and therefore there was vague knowledge about the correlation between liquid crystalline properties and structural factor. The results from our research indicated the mechanism of molecular designing which is still remain unknown. The side chain group of synthesized liquid crystalline polymers could be controlled, and therefore the liquid crystalline polymers are expected for usage as polymer laminated films and polymer materials with high order regulated structures.
