Phase separated domain structure of poly(vinyl butyral)

  • Published:
Polymer Bulletin Aims and scope Submit manuscript

Summary

A morphological study of poly(vinyl butyral) is performed on the thin films prepared by evaporation of polymer solutions. It is shown by transmission electron microscopy that there are many domains of dimensions 0.02 to 1 μm in this amorphous random copolymer. The image contrast of the electron micrographs is improved significantly by RuO4 staining technique. It is suggested that the domain structure can be mainly attributed to the hetrogeniety of the polymer as a result of microphase separation in the polymer solutions.
