Abstract
A monomer 4,4'-bis(β-hydroxyethyl)biphenyl (2BP) was synthesized by the Williamson reaction from 2-chloroethanol and 4,4'-biphenol. Then, the novel dendritic liquid crystal macromolecule (DLCM) containing biphenyl structure was synthesized with 2BP and 1,3,5-benzenetrimethylacylchloride as monomers by dispersion method. The structures of 2BP and the DLCM were characterized by FT-IR and 1H-NMR. The thermal stabilities of he DLCM were measured by TGA and DSC. The results showed that the DLCM had good thermal stability and the DLCM may have a higher phase inversion temperature.
