We prepared a novel fluorinated polymer from a bicycloacrylate monomer, (1 H ,1 H ,2 H ,2 H )‐perfluorododecyl 2‐(bicyclo[3.1.0]hex‐1‐yl)acrylate, by radical ring opening polymerization. The bulk properties of the polymer were investigated by thermal analysis and X‐ray diffraction, which proved the existence of a smectic mesophase up to the isotropization temperature of 74 °C. Furthermore, a solid state NMR study was started to characterize domains with different mobility mainly by 13 C cross‐polarization magic angle spinning and T 2 selective experiments. We found that the polymer is a homogeneous sample with the presence of dynamic motions in the kHz regime below the glass transition temperature.
