Maintaining constant gas composition in a gas phase polymerization is crucial for a
uniform polymerization process and the development of new polymers. Due to the
typical conditions in a polymerization chamber ( T ≈ 340K, p ≈ 2.5*10^6 Pa ), standard
procedures such as mass spectrometry or gas chromatography cannot be applied to
directly monitor the gas composition inside a reaction chamber in real-time.
We are currently developing a density sensor for real-time measurements inside a
reaction chamber, which will be part of a sensor system for monitoring the gas
composition during a polymerization process.
