Polymers & Plastics
Vibrational spectroscopy (Infrared, Near Infrared and Raman) has been widely used for the analysis and characterization of polymers. Infrared spectra of polymers give insight at the molecular level as to the orientations and conformations of the polymer chains. Fourier Transform Infrared spectroscopy has proven to be the simplest and most informative way to obtain spectra of polymers. To date, most IR measurements of polymers have been recorded under static conditions. However, since IR spectra can reflect the subtle changes in molecular structures of the polymer chains due to external perturbations, there has recently been increasing interest in investigating the dynamic properties of polymer films using infrared spectroscopy; the external perturbation of greatest interest is imposing a repeatable dynamic strain on the polymer. The dynamic difference IR spectra thus obtained can provide information as to the reorientations and the conformational changes of the polymers.
FT-IR Microanalysis and Imaging now offers a unique opportunity to analyze polymer formulations, multi-layer polymer films and composite materials.
The new minispec mq-one TD-NMR Polymer analyzer provides complete quality control turn-key analysis solutions, such as:
