Mesomorphous polymers with side chains containing a motive of trans(phenylene 4-4' substituted)-2 dioxane 1,3 alkenyl-5. |
| 摘要 |
<p>The invention relates to a new class of liquid crystal polymers with a high glass transition temperature. These polymers correspond to the following general formula: <IMAGE> x denoting the degree of polymerisation X being <IMAGE> or <IMAGE> Y being CN, CF3 or OCH3 and 2 </= n </= 12. Applications to the production of components in the nonlinear optics field.</p> |
