Homogeneous copolymers liquid mixtures

Stabilizer precursors can be used in conventional dispersion polymerization only because the starting reaction mixture is homogeneous. Some nonaqueous dispersions, however, are made by processes in which one or more of the reactants is/are insoluble in the liquid diluent (e.g., polycondensation) [3.70]. In these cases, preformed graft copolymers must be used because they function not only as stabilizers for the final dispersion, but also as dispersants or emulsifiers for the starting materials. 

The above-mentioned equations make it possible to predict the equilibrium conditions for any initial conditions, provided the standard free energies of comonomer additions are known. It is worth adding here that these thermodynamic functions are in fact AssG parameters referring to comonomers and a copolymer dissolved in the reaction mixture (however, some authors treat homogeneous bulk copolymerization as the Ic process liquid comonomers converted to an amorphous copolymer). 

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.
