Abstract
The thermal and liquid crystalline properties of comb-shaped polymers, having side-groups with an azo dye unit, were estimated by DSC and polarizing microscopy. The liquid crystalline comb-shaped polymers (LCP) showed a smectic phase with a focal conic fan texture on heating and cooling. LCP with an amide terminal group in the side-chain exhibited a 62°C higher glass transition point than LCP with nitro terminal groups and the thermal decomposition at 300.0°C, which is lower than an isotropization temperature.
