Abstract
Thermotropic random copolyesters containing 2,2′-biphenylene rings, disclike mesogens in the polymer chain, were synthesised by the polycondensation method and characterised by viscosity measurements, and spectral analysis. Thermal properties of these polymers were investigated by DTA and DSC studies. The LC behaviour of these polymers were studied by optical polarising microscopy in conjunction with WAXD studies. Structural modifications introduced along the main chian changed the type of mesophase probably due to polar and interlocking effects.Keywords
