| Abstract: | The synthesis and properties of a series of new ferroelectric liquid crystal side-chain polymers with the same mesogenic side group but different polymer backbones (polyacrylate, polymethacrylate and polysiloxanes) are described. The polymorphism is studied by optical microscopy, differential scanning calorimetry and X-ray diffraction. All the monomers exhibit at least an SA and a ferroelectric S*C phase, as the polymethacrylate and the copolysiloxane. These two polymers and the polyacrylate exhibit also an S*F phase. © 1997 John Wiley & Sons, Ltd. |
