  • Crosslinked organopolysiloxanes having liquid-crystalline properties
    Patent number: 4388453
    Abstract: This invention relates to crosslinked organopolysiloxanes having liquid-crystalline properties in which mesogenic molecules are chemically bonded to the organopolysiloxane lattices. These crosslinked organopolysiloxanes are prepared from silanes or siloxanes containing mesogenic molecules which are capable of being crosslinked by addition or condensation reactions.

  • Compositions containing liquid crystal phases
    Patent number: 4358391
    Abstract: Compositions having liquid crystal phases which contain at least one component consisting of an organopolysiloxane having mesogenic molecules chemically bonded thereto as side chains which are obtained by grafting vinyl-substituted mesogenic molecules to an organohydrogenpolysiloxane. The organopolysiloxane backbone may also carry different molecules, such as nematogenic and cholesterogenic or chiral molecules, as side chains.
