We investigate the possibility of online-monitoring of a gas phase polypropylene polymerization by
application of infrared absorption measurement. It is demonstrated that, even though the absorption
coefficients depend on pressure and gas composition when measuring at typical polymerization conditions,
the composition of a gas mixture can be accurately determined by application of modern evaluation
algorithms. Furthermore, a potential simplification of the measurement system (by building dedicated
systems, which measure at specific wavelengths only) is identified.
