Ordered structures of poly(1H,1H,2H,2H‐perfluorodecyl α‐fluoroacrylate) (P17FF), poly(α‐chloroacrylate) (P17FC), poly(methacrylate) (P17FM) and poly(acrylate) (P17FA) were investigated by X‐ray diffraction, DSC and polarizing microscopic observations. At room temperature, both P17FF and P17FC prefer the layered structure of single‐layer packing of the fluoroalkyl side chains, while P17FM contains both single‐layer and double‐layer packing, and P17FA forms double‐layer packing. As temperature increases, particularly in P17FF and P17FC, there was observed a structural rearrangement of the single‐layer packing to double‐layer one accompanied by melting of the side chain crystallites, which may come from an intermolecular interaction between the main chains caused by polar effect of the α‐substituents.
