The synthesis and characterization of polymethacrylate, polyacrylate, poly(methylsiloxane), and 1,3,5,7‐tetramethylcyclotetrasiloxane containing chiral 4‐[2‐(S)‐methyl‐1‐ butoxy]‐4′‐(11‐undecanyl‐1‐oxy)‐α‐methylstilbene side groups are described. All polymers exhibit an enantiotropic SA mesophase and side‐chain crystallization. The 1,3,5,7‐tetramethylcyclotetrasiloxane containing mesogenic side groups represents a mixture of four stereoisomers and displays a monotropic SA mesophase
