摘要: by high pressure treatment at temperature. Evidence for crosslinking is presented on the basis of X-ray diffraction pattern, infrared absorption, ultraviolet-visible absorption spectra. As was observed in C60 polymers, C70“polymerrdquo; not soluble toluene, and revert to conventional monomer crystals heating \valunit{300}{\celsius} ambient pressure.
