摘要

<正> Magnetic field-induced orientation of a chiral side chain liquid crystalline polyacrylate（P-11） was studied by using IR dichroism. For the investigated P-11

it has been shown thatthe magnetic alignment takes place over the entire temperature range between its meltingpoint and clearing point and the orientation level is strongly temperature-dependent

thedevelopment with time of the magnetic orieatation follows an exponeotial-type relation

and the smectic phase state influences the thermal relaxation process in the absence of themagnetic field.
