Can anyone explain the formation of graphatic structure from the carbonization of NBR ? Is there any mechanism relevant for this formation?

I need to carbonize the NBR rubber sample. Can anyone explain the formation of graphitic structure from the carbonization of NBR? Is there any mechanism relevant for this formation?

Mike Hale

The yield of carbon will depend on the acrylonitrile (ACN) content of the polymer and is generally quite low (~12% for a 50% ACN NBR). The mechanism is very broadly as described for the manufacture of carbon fibre from polyacrylonitrile. If the Nitrile rubber is carbon black filled, then this will also contribute to the Carbon yield, as might polymeric plasticisers.
