A series of optically active mesogen-jacketed liquid crystal polymers with nagrow polydispersities(P-1～P-6) were studied by a combination of static and dynamic laser light scattering techniques and viscosity measurements in．THF at 25℃．It is found that THF is a good solvent for the polymers studied．The dependences of the intrinsic viscosity [η] and root mean-square radius of gyration2g>z1/2 of the polymers on weight-average molecular weight Mw are[η]=(2.75±0.05)×10-3 Mw0.78±0.02 and g2>z1/2=(1.53±0.04)x10-2 Mw0.60±0.01

respectively

in THF at 25℃．According to Bohdanecky-Bushin’s method based on Yamakawa-Fujii-Yoshizaki’s theory for worm-like chain cylinders

the molar mass per unit contour length ML and the persistence length q were estimated to be(29．8±1.0)×102 nm and (15.4±3.0) nm．respectively．The values of the exponent a of Mark-Houwink-Sakurada equation and q indicate that these liquid crystal polymers of the side-chain type have an extended conformation in dilute solutions as most nlain-chain liquid crystal polymers.
