Mesomorphic side-chain polymers having high dielectric anisotropy and a method for producing said polymers |
| 摘要 |
The invention relates to a family of sidechain homopolymers of the polyacrylate type derived from 3-fluoro-4-cyanophenol and exhibiting a mesophase of the nematic or smectic-A type. The polymer in accordance with the invention corresponds to the following general chemical formula : <IMAGE> where x indicates the degree of polymerization and 4</=n</=15.
