  Vinyl-Substituted Liquid Crystal Dimers

  摘要：

  A series of vinyl-substituted liquid crystal dimers, -(4-cyanobiphenyl-4'-yloxy)alkyl 4'-(4-pentenyloxy)-4-biphenylcarboxylates, was prepared. The compounds exhibited nematic and smectic liquid crystalline behavior depending on the chain length of the flexible spacer. The nematic-isotropic and smectic-isotropic transition temperatures and the entropy changes associated with the transitions showed odd-even effects as the number of atoms in the flexible spacer was varied, in which the even members exhibited higher values. The liquid crystalline properties of the compounds were compared with those of related known liquid crystal dimers and trimers.

  Benzoxazine monomers comprising at least one pendant group are described. (Co)Polymers comprising at least one benzoxazine monomer having at least one pendant group are also described. In a preferred embodiment, the pendant group is located in a side chain of the benzoxazine monomer or polymer. Methods for preparing the benzoxazine monomers and polymers are described. Compositions comprising the benzoxazine monomers and polymers have numerous uses including optical materials, and in electronic materials as electrically insulating materials, and as fireproof materials.
