Chemical recycling of cycloolefin-copolymers (COC) in a fluidized-bed reactor

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.
