series of liquid crystalline and non-liquid-crystalline sequential copolymers was synthesized by radical polymerization of styrene and the mesogenic monomer. The liquid crystalline behavior of the copolymers was studied by DSC
polarized optical thecroscopy and X- ray diffraction. It was found that the mesogenic monomen and all copolymers except the CP -9
showed good thermotropic liquid crystallinity and broad temperature ranges between T8 and Ti
The molecular weights
transition temperatures and decomposition temperatures of the copolymers changed regularly with the increase of the contents(mol%)of styrene in the copolymers.
