“…OsO 4 reacts with double bonds in the rubber, resulting in increase of brittleness of the rubber particles and contrast between the rubber and matrix. 2,3 It is known that TEM micrographs from the stained specimens show not only dark rubber particles but also dark crazes (named "black crazes" here), [4][5][6] in contrast to the surrounding matrix. Kambour and Russell 7 reported that OsO 4 also reacts with craze fibrils, which increases contrast between the craze structure and the surrounding matrix.…”

Black crazes — white crazes?

The origin of the curious "inverted contrast" often observed in transmission electron micrographs of crazes in rubber-toughened thermoplastics was determined by using scanning transmission electron microscopy with X-ray fluorescence analysis. The "black crazes" seen in the micrographs contain high concentrations of osmium metal which is introduced through OsO, used to stain the rubber phase. Treatment of stained sections with a strong oxidizing agent (NaI0,) removes a sufficient amount of osmium to reveal the commonly observed tufty craze microstructure with the expected contrast of light crazes in a darker background.

Interpenetrating polymer networks of polyurethane and unsaturated polyester were prepared by reaction injection molding (RIM) and transfer molding. The structures of the molded samples were analyzed by electron microscopy and dynamic mechanical analysis. It was found that polymer morphology and dynamic mechanical properties depend strongly on the molding temperature, reaction rate and reaction sequence. Simplified structure models based on Takayanagi's model and sample morphology can predict the storage modulus reasonably well but not the tans.
