Paper Abstract

With the introduction of the Fourier-Transform technique in the mid-seventies, infrared spectroscopy has become one of the most important tools for the characterization of the chemical and physical nature of polymers. Apart from the increa­sing availability of a broad range of special sampling devices and detection techniques (attenuated total reflection, photoacoustic and micro­spectroscopy) in the course of the years, the following development of the step-scan technique and the extension from the mid- to the near-infra­red (NIR) region have had the most significant impact on the applicability of IR-spectroscopy for time-resolved polymer analysis and process control In the following contribution the principles and experimental details of the new techniques will be discussed and selected applications from various fields of polymer research shall demonstrate their potential.­­­
