Abstract

An analytical method for determination of polyurethane content in modified polyoxymethylene (POM) by nuclear magnetic resonance (NMR) spectroscopy was established in this paper. Specifically, the samples were dissolved in the deuterated reagent, followed by being tested by 1H-NMR spectroscopy. Next, the characteristic peaks of POM and polyurethane were integrated, and the polyurethane content in modified POM was obtained by integral area ratio. This method, featuring the advantages of a high accuracy, simple and fast operations, and no nominal samples required, has a relative standard deviation of < 2%, and its correlation coefficient with actual results was 0.9993.
