摘要： A vinyl acetate-ethylene (VAE) copolymer and uses of the same are provided. The vinyl acetate-ethylene (VAE) copolymer includes a structural unit derived from ethylene and a structural unit derived from vinyl acetate. The 1H-NMR spectrum of the vinyl acetate-ethylene (VAE) copolymer has an integral value B of signals from 0.5 ppm to 1.0 ppm and an integral value A of signals from 4.6 ppm to 5.0 ppm, and the value of B/3A ranges from 0.070 to 0.120. The 1H-NMR spectrum is measured by using dimethyl sulfoxide as a solvent.
