Abstract

The invention relates to reversibly crosslinked, orientable liquid crystalline (LC) polymer films, comprised of an LC poly(meth)acrylate PP and/or a mixture of PP with low molecular weight crosslinking components. The inventive films have numerous applications, e.g. for optical information storage, and for surface coatings, laminates, or bonded systems having special anisotropic properties.
