What is NMR Study of Poly(ethylene-co-vinyl acetate) about?

This document summarizes a study that used NMR spectroscopy techniques to characterize poly(ethylene-co-vinyl acetate) (EVA). Solution NMR was used to determine the copolymer composition was 13% vinyl acetate. Solid-state NMR techniques including MAS, CPMAS and variable contact time experiments revealed the presence of two distinct domains - one of rigid ethylene sequences and one of flexible ethylene sequences and vinyl acetate groups. The variable contact time experiment showed the differences in mobility
