Abstract
A chloroprene polymer having a structural unit derived from chloroprene and a structural unit derived from an unsaturated nitrile, in which the chloroprene polymer has a peak top at 5.80 to 6.00 ppm in a 1H-NMR spectrum as measured in a deuterochloroform solvent, in the 1H-NMR spectrum, a peak area ratio A/B of a peak area A at 5.80 to 6.00 ppm and a peak area B at 4.05 to 6.20 ppm is more than 1.1/100 and 2.3/100 or less, and a content of the structural unit derived from an unsaturated nitrile is more than 0% by mass and 23% by mass or less.
