As a part of our effort to synthesize biopolymers from a completely renewable material source (di-linoleic diol), novel techniques of polymerization are used, e.g., Reversible Radical Recombination Polymerization (R3P). Besides methods of polymerization, analytical techniques are also being constantly developed. Recently, IR spectroscopy was successfully used to continuously monitor the process of chromatographic monomer purification. The resulting chromatogram simultaneously shows the time dependence and the wavenumber dependence of IR absorbances.
In practice, the technology can facilitate the real-time recording of the IR spectra of the analytes at any arbitrary retention time.
