✦ Synopsis

The pyrolysis of cycloolefin-copolymers (COC) in a fluidized-bed reactor was studied under various parameters like pyrolysis temperature, fluidizing gas or residence time. It was proven to reduce the undesired tar fraction to a minimum of around 10 wt.% and to obtain up to 44 wt.% valuable gases and 45 wt.% aromatic light oils with a reactor temperature of 700 8C.

Furthermore, the mechanism of the pyrolytic degradation has been analyzed to determine if the comonomer 2-norbornene can be obtained by pyrolysis. In all experiments, only traces of around 0.05 wt.% were detected. It was learned that 2-norbornene is not stable enough to resist drastic pyrolysis conditions; rather it undergoes a Retro-Diels-Alder reaction to form ethene and cyclopentadiene.
