AB  - Chemical recycling processes, such as pyrolysis, have the potential to break down the polymer (e.g., polymethyl methacrylate, PMMA) into its main building blocks (monomers), and thus enable to preserve the full functionality in closed-loop recycling processes. In this study, products from flash pyrolysis of PMMA are quantitatively determined using an ex-situ exhaust gas analysis by means of Fourier-transform infrared (FTIR) spectroscopy. To achieve this, the FTIR is additionally calibrated for methyl methacrylate (MMA) with an MMA/N2 mixture of various concentrations. Flash pyrolysis conditions (heating rates of approximately 1000 K/s are realized with a small-scale fluidized bed reactor operated with a nitrogen atmosphere and temperatures between 573 and 873 K with a continuous feed of PMMA granules. The experiments reveal MMA yields up to 90
