[Problem] To obtain a latex for dip molding having satisfactory characteristics without causing production problems such as agglomerates and adhesion of scales to reactor can walls even when the monomer concentration is increased. Provided is a method for producing a dip-forming latex. A monomer having a specific composition comprising a conjugated diene monomer, an ethylenically unsaturated nitrile monomer, an ethylenically unsaturated acid monomer, and other ethylenically unsaturated monomers copolymerizable therewith. A method for producing a latex for dip molding in which a body is copolymerized, and (1) a monomer comprising a specific ratio of all monomers used and having a total amount of ethylenically unsaturated acid monomers used for polymerization The first stage of polymerization is started using an initial polymerization monomer containing a specific ratio, and (2) a specific amount of an additional emulsifier is polymerized when the polymerization conversion rate of the initial polymerization monomer is within a specific range. (3) After completion of the addition of the emulsifier, the remaining monomer is sequentially added to the polymerization system to carry out the second stage polymerization. [Selection figure] None |
