Beschreibung
Zusammenfassung:	A chloroprene-based polymer latex, and a chloroprene-based polymer, which can obtain an adhesive composition that generates less aggregates during and after the polymerization reaction and does not cause layer separation for a long period of time, and an adhesive composition, a compound composition, and a vulcanized molded body containing such a chloroprene-based polymer latex or a chloroprene-based polymer, and a method for producing these, are provided.According to the present invention, a chloroprene-based polymer latex comprising a chloroprene-based polymer, wherein: an amount of substance of alkali metal cation per unit mass in the chloroprene-based polymer latex is 0.05 to 0.12 mmol/g, when the chloroprene-based polymer latex is freeze-dried to obtain a solid content containing the chloroprene-based polymer, and an ethanol-toluene azeotropic mixture soluble content specified in JIS K 6229 is extracted by refluxing from the solid content to obtain an extract, and the obtained extract is acid treated with hydrochloric acid, an amount of rosin acid of in the solid content measured by gas chromatography is 1.4 to 4.2% by mass with respect to 100% by mass of the chloroprene-based polymer in the solid content, is provided.
