AbstractThe High‐Output Polymer Screening (HOPS) combines process‐relevant automated reactor systems and rapid polymer characterization with on‐line polymerization monitoring and automated data acquisition (“electronic notebook”) in order to make effective use of advanced data mining tools. This has led to the development of fingerprint technology based upon correlations between spectroscopic data and polymerization process conditions, catalyst compositions, as well as polymer end‐use properties. Infrared spectroscopic fingerprints proved to be very useful for accelerating polymer analyses including characterization of polymer molecular architectures as well as non‐destructive testing of the mechanical, thermal and other end‐use polymer properties. Such spectroscopic fingerprints represent important components of effective on‐line quality control systems. With ATR‐FT‐IR probes on‐line monitoring of catalytic olefin copolymerization was performed in solution to measure in real time copolymerization kinetics, catalyst productivities, catalyst deactivation as well as copolymerization parameters and copolymer sequence distributions. Monomer consumption and comonomer incorporation were monitored simultaneously. Advanced fingerprint technology can reduce significantly the need for time‐ and money consuming polymer testing and can also stimulate the search for new catalyst systems and polymeric materials.
