Abstract:
A chiral compound of formula I: in which:A1, A2 and A4each independently represents hydrogen; an optionally-substituted methyl group; an optionally-substituted aliphatic group with 2 to 80 C-atoms, in which one or more C-atoms may be replaced by a heteroatom, in such a manner that oxygen atoms are not linked directly to one another; or an optionally-substituted aromatic ring system, with 1 to 80 C-atoms; and A3 represents an optionally-substituted aliphatic group with 2 to 80 C-atoms, in which one or more C-atoms may be replaced by a heteroatom, in such a manner that oxygen atoms are not linked directly to one another; or an optionally-substituted aromatic ring system, with 1 to 80 C-atoms; wherein at least one of the A1 to A4 residues includes a polymerisable group, with the proviso that, when the only polymerisable group is in the A3 residue, the polymerisable group does not comprise a C=C group directly connected to the carbon atom linking A3 and A4.
