Following UV Induced Chemical Reactions with Rheometry and Simultaneous FTIR-Spectroscopy — •Jan Philip Plog1, Veit Zschuppe1, and Manfred Feustel2 — 1ThermoFisher Scientific, Dieselstraße 4, 76227 Karlsruhe, Germany — 2Resultec, Gartenstraße 23, 89171 Illerkirchberg, Germany
In this article a new and unique combination of a rheometer and an FTIR-spectrometer is presented. The so-called Rheonaut module allows the coupling of the Thermo Scientific HAAKE MARS rheometer platform with an FTIR-spectrometer. With this set-up, samples can be characterized rheologically using cone/plate- or plate/plate-geometries while IR-spectra are being recorded simultaneously. To test this new concept, UV induced polymerization and cross-linking reactions have been followed with the combination of HAAKE MARS and the Rheonaut module. Depending on the chemical nature of the components involved, the disappearance of the starting materials reactive group and/or the appearance of chemical groups, which are characteristic for the product can be seen and correlated with the development of the mechanical properties. Details of this unique instrument set-up as well as selected results will be presented.
