X-ray diffraction patterns of ABPBIPBT polyblend films suggest the formation of polymer-solvent complexes at the molecular level. This effect may be misinterpreted as a new phase formed as a result of blending the two polymers. Polymer-solvent complexes are crystalline and can be oriented by usual methods. The nature of the x-ray diagram of the polymer-solvent complex depends upon blend composition, type of solvent and the method employed for film processing casting or quenching. Neutralizing or annealing of polyblend films in order to eliminate the solvent results in x-ray diffraction patterns which can be explained in terms of additive contributions from the constituent polymers, the ABPBIPBT polyblend films thus have a two-phase morphology. Various methods for the processing of these novel polymer mixtures are presented and discussed in terms of their influence on the microstructure.
