Chirally nematic polyesters |
| 摘要 |
Liquid crystalline chiral nematic polyesters have flexible chains comprising isosorbide, isomannide and/or isoidide units. The polyesters are not crystalline and form stable Grandjean textures which can be frozen on cooling below the glass transition temperature. They can therefore be used in particular as surface-coating materials.
