Title:
CHLOROPRENE POLYMER, CHLOROPRENE POLYMER COMPOSITION, VULCANIZATION MOLDED BODY AND ROLL
Document Type and Number:
WIPO Patent Application WO/2022/215411
Kind Code:
A1
Abstract:
A chloroprene polymer which has a structural unit derived from chloroprene and a structural unit derived from an unsaturated nitrile, wherein: the 1H-NMR spectrum of this chloroprene polymer as determined in a deuterated chloroform solvent has peak tops at 5.80 to 6.00 ppm and at 5.10 to 5.30 ppm; with respect to the 1H-NMR spectrum, the peak area ratio of the peak area A of 5.80 to 6.00 ppm to the peak area B of 4.05 to 6.20 ppm, namely A/B is from 0.9/100 to 1.1/100; the peak area A, the peak area B and the peak area C of 5.10 to 5.30 ppm satisfy formula (C - 2A)/B ≤ 2.0/100; and the content of the structural unit derived from an unsaturated nitrile is more than 0% by mass but not more than 23% by mass.
