Mesomorphous polymers with side chains containing a motive of trans (phenylene 4-4' substituted)-2 dioxane 1,3 alkenyl-5.

摘要

The invention relates to a new class of liquid crystal polymers with a high glass transition temperature and capable of exhibiting a nematic phase and/or a smectic phase. The polymers are of the polyacrylate type and contain a trans-2-(4-cyanophenyl)-1,3-dioxan-5-yl unit. Applications to the nonlinear optics field.
