## Abstract New photo‐crosslinkable side‐chain liquid‐crystalline methacrylate polymers comprising __m__‐[4′‐(__n__‐cinnamoyloxyalkoxy)biphenyl‐4‐yloxy]alkyl groups (__m__, __n__ = 2, 6) were synthesized. All polymers exhibit a nematic liquid‐crystalline phase depending on the spacer length (5a–5d)
Side group liquid‐crystalline polymers (SG‐LCP) will need to be macroscopically oriented if the applications foreseen for them are to be realized. The first observation of oscillatory‐sheer‐induced alignment of an SG‐LCP melt (the Figure shows a schematic of the rheo‐optical apparatus used) is repor
