To explore the effect of molecular packing in a liquid-crystalline phase on property of polymer produced, we conducted photopolymerization of a ferroelectric liquid-crystalline (FLC) methacrylate monomers with a polymerizable group attached to the rigid core through a short methylene spacer (carbon number of 2) and a long methylene spacer (carbon number of 11). Photopolymerization was performed in a glass cell with a gap of 2 μm without an electric field or under a 3 V/μm dc electric field. It was found that the application of the electric field is more effective in the polymerization of FLC monomer having a short spacer. Furthermore, the tacticity and thermal property of polymer produced, and the relationship between layer distance and polymerizability were also investigated.
