Abstract
A method for producing a hydrogenated conjugated diene polymer latex includes: a hydrogenation step of dissolving or dispersing a hydrogenation catalyst containing a platinum group element in a latex of a conjugated diene polymer to hydrogenate a carbon-carbon unsaturated bond in the conjugated diene polymer; and an insoluble complex formation step of complexing the platinum group element in the latex with a complexing agent to form an insoluble complex, wherein pH of the latex at the insoluble complex formation step is controlled in a range of 5.0 to 8.0.
