LCPBDs were made by radical addition of thiol group onto the double bonds of PBD with various initial molar ratios of thiol to double bonds. Thermal structural transitions in LCPBDs are investigated by DSC, WAXS and polarizing microscopy, the broadband dielectric spectroscopy is used for investigation of molecular dynamics in these LCPBDs.
