NMR spectroscopy enables the precise analysis of polymer structures, polymerization mechanisms and material properties. It helps to identify impurities and additives and is indispensable for research, quality control and the development of new materials. NMR helps to check purity and homogeneity and to identify impurities.
NMR spectroscopy (nuclear magnetic resonance spectroscopy) is an indispensable tool in polymer research. It enables the precise determination of the molecular structure and configuration of polymers. By analyzing the chemical shifts, the tacticity and sequence distribution of polymers can be investigated, which is crucial for the characterization of their physical and chemical properties.
One of the main applications is the identification of additives and impurities, which is of great importance for the production of high-performance polymers. If the concentration of the additive is sufficient, the additive can be detected or identified directly in the polymer matrix or the plastic matrix. Here, investigations of heteronuclei also lead to a positive identification, for example 31P-NMR spectroscopy or 19F-NMR spectroscopy.
For identification, we use our extensive database, which contains the spectra of many additives in pure substance.
In quality control, NMR spectroscopy is used to check the purity and homogeneity of polymer samples. It can also make an important contribution to the analysis of recycled materials and complaints. NMR spectroscopy of polymers does not require complex sample preparation and method development. It is a good starting point for providing an initial estimate of the polymer composition and developing ideas for further analysis.
In summary, it can be said that NMR spectroscopy is a versatile and powerful tool in polymer research that makes decisive contributions to the development and optimization of polymers.
