Abstract
A chloroprene-based polymer, wherein: a 1H-NMR spectrum of the chloroprene-based polymer measured in a deuterochloroform solvent has a peak at 5.80 to 6.00 ppm; when an area of the peak at 5.80 to 6.00 ppm is A and an area of a peak at 4.05 to 6.00 ppm is B, A/B is 1.20/100 or less; the 1H-NMR spectrum of the chloroprene-based polymer measured in a deuterochloroform solvent has a peak at 5.40 to 5.60 ppm; when an area of the peak at 5.40 to 5.60 ppm is D and the area of the peak at 4.05 to 6.00 ppm is B, D/B is 97.20/100 or less, is provided.
