Document Type and Number:
WIPO Patent Application WO/2020/095962
Kind Code:
A1
Abstract:
A chloroprene/unsaturated nitrile copolymer which contains 3-20 mass% of a structural unit derived from an unsaturated nitrile monomer and, in a 1H-NMR spectrum measured in a heavy chloroform solvent, which has a peak at 5.80-6.00 ppm and shows a ratio (A/B) [wherein: (A) stands for the peak area within the range of 5.80-6.00 ppm; and (B) stands for the peak area within the range of 4.05-6.20 ppm] of 0.6/100-1.1/100.
