Linearly polarized (LP) UV photoreaction of a photo-crosslinkable sidechain liquid-crystalline polymer (SLCP) containing photoreactive cinnamoyl and biphenyl mesogenic groups ( 1) was studied. The optical anisotropy of the polymer film was induced by the LP-UV photoreaction and was investigated by t
## Abstract Thermal relaxation behavior of a mechanically induced macroscopic orientation of the mesogenic groups in a sideβchain liquid crystalline polyacrylate was investigated using timedependent polarized infrared spectroscopy. It was found that a complete relaxation occurred only at temperatur
