TRANSMISSION ELECTRON MICROSCOPY OF SEGMENTED POLYURETHANES WITH RUTHENIUM TETROXIDE AS A STAINING AGENT

Received Date: 4 September 1990

Microphase separation and lamellar structure of segmented polyether-and polyester-polyurethanes have been investigated by means of transmission electron microscopy with the ruthenium tetroxide staining technique. The results show that the RuO4 staining technique is simpler and may give better image contrast than other staining methods for this polymer. Microphase separation and lamellar structure of segmented polyether-and polyester-polyurethanes were directly observed and discussed.
