Automated Ultra-Fast ¹³C NMR Analysis of Polyolefin Materials.

ABSTRACT: Polyolefins are unique among synthetic polymers because their wide application envelope originates from a finely controlled microstructure of hydrocarbon chains, lacking any distinctive functional groups. This hampers the methods of automated sorting based on vibrational spectroscopies and calls for much more complex ¹³C NMR elucidations. High-temperature cryoprobes have dramatically shortened the acquisition time of ¹³C NMR spectra, and few minutes are now enough for polyolefin classification purposes; however, conventional data analysis remains labor and time-consuming. In this paper, we introduce an instrument for automated fast determinations of the ¹³C NMR microstructure on polyolefin materials, implemented by integrating High-Throughput Experimentatio
