Abstract:
1. A compound according to formula I wherein R R Y P is a polymerizable group, Sp is a Sp′-X′ or a single bond, Sp′ is alkylene with 1 to 20 C atoms, which is optionally mono- or polysubstituted by F, Cl, Br, I or CN, and wherein one or more non-adjacent CH X′ is —O—, —S—, —CO—, —COO—, —OCO—, —O—COO—,—CO—NR A and B are independently of each other 1,4-cyclohexylene wherein one or more —CH b is 0 or 1; wherein at least one of R 1 and R 2 is P-Sp′-X′ is not a single bond, and if only one of R 1 and R 2 is P-Sp′-X′— then X′ is not —O— or —CH 2 O— and Sp ′ is not an alkylene with 1 20 C atoms wherein only one CH 2 group is replaced and it is replaced by —O—; with the proviso that compounds wherein; b is 0, R P is arcylate or methacrylate, and Sp is a single bond or a —CH are excluded.
