Phenylbenzoate-anthraquinone copolymers

For the phenylcyclohexane-anthraquinone copolymers and the biphenyl-anthraquinone copolymers examples are given in Table 1 and compared with a phenylbenzoate-anthraquinone copolymer. 

Mixtures of the Anthraquinone Monomer, the Phenylbenzoate-Anthraquinone Copolymers with the Binary Phenylbenzoate Host Mixture... 

Miscibility studies of the nematic dye-containing copolymers with suitable low molecular weight liquid crystals yield homogeneous nematic mixtures. A binary mixture of 4-cyanophenyl-4-heptylbenzoate and 4-cyanophenyl-4-pentylbenzoate is miscible with the phenylbenzoate-anthraquinone copolymers. 

The phenylbenzoate copolymers with the anthraquinone dye form nematic phases which decrease with increasing content of the dye monomer as shown in Fig. 2. The copolymer with an anthraquinone monomer content of about 39 % by weight is no longer liquid crystalline.
