A new series of chiral shish-kebab type liquid crystal block copolymers that form the smecticC(Sc*) phase was synthesized by solution polycondensation. The copolymers were characterized by GPC.DSC. TG

POM. X-ray diffraction and polarimeter. The copolymers 7 entered into liquid crystal phase whenthey were heated to their melting temperatures (Tm) and the copolymers 8 were in liquid crystal phase at roomtemperature with low viscosities. The smectic sanded texture or focal-conic texture were observed on POM.All the chiral block copolymers showed high optical activity .No racemization has happened.Temperature-variable X-ray diffraction study together with POM and polarimetric analysis realized that they are chiral smecticC(Sc*) phase.Thus we offer in this report the first example of shish-kebab type liquid crystal block copolymers that from a chiral smectic C(Sc*)phase.The variation of melting and isotropization temperatures with molecular structure was also discussed.
