The present invention provides a polychloroprene latex capable of obtaining a dip-molded film having flexibility and excellent mechanical properties. A thiol-modified polychloroprene latex comprising polychloroprene as a copolymer of chloroprene and 2,3-dichloro-1,3-butadiene, in In the 13C-solid NMR spectrum of the above-mentioned polychloroprene obtained by freeze-drying the modified polychloroprene latex, the peak area (A) of 126.2 to 127.6 ppm, the peak area of 122.0 to 126.2 ppm (B), The peak area (C) of 129.9 to 130.3 ppm is in the range represented by the following general formula (I), relative to the chloroprene and 2,3-dichloro-1,3- The total amount of butadiene is 100% by mass, the copolymerization amount of 2,3-dichloro-1,3-butadiene is 4 to 35% by mass, and the toluene insoluble matter of the aforementioned polychloroprene is contained in the aforementioned polychloroprene 100 In mass %, it is 50-100 mass %. |
