Utilizing PGSTE diffusion measurements for molecular weight determination by benchtop NMR In a previous application note, we discussed how the molecular weight of two PDMS polymers can be measured via end-group analysis in 1D ²⁹Si-NMR. Building on that discussion, this study focuses on the use of diffusion NMR spectroscopy to determine the molecular weight of …

Maximizing signal-to-noise ratio per measurement time by using the advantages of magnetization transfer in 29Si–1H-HMBC spectra. In a previous application note we discussed how the copolymer composition and average molar mass of poly(dimethylsiloxane-co-methylhydrosiloxane), trimethylsilyl terminated (Figure 1) can be determined by 29Si-DEPT NMR spectra and using a well characterized sample of the same substance as …
