| abstract |
The invention relates to an organic polymer having a fixed polar structure which is characterized in that it consists of a densely cross-linked polymerization product of monomers, for which monomers it holds that a) at least a part of the monomers exhibit a tilted smectic phase, b) at least a part of the monomers have one or more chiral centres, c) at least a part of the monomers are provided with one or more electron-donating and/or electron-accepting groups so that a polar axis exists transversely to the longitudinal direction of the monomers, and d) the monomers are provided with polymerizable groups, intended for cross-linking and chosen among acrylate, methacrylate, styrene or other polymerizable groups intended for cross-linking. The invention also concerns a process for producing the polymeric material and use thereof in optical components. |
