    Abstract: A method for producing a chloroprene-based polymer composition including a polymerization step, wherein chloroprene, or chloroprene and a monomer copolymerizable with chloroprene are polymerized; and includes monomer and emulsifier addition steps, when a total amount of monomer used in the polymerization step is 100%, an initial addition amount of monomer at start of polymerization is X %; in the monomer addition step, when the initial addition amount of the monomer is 100%, a remaining monomer is added to the polymerization system from time when polymerization progresses and Y % of the monomer initially added converts, by reaching the polymerization completion conversion; in the emulsifier addition step, when the total amount of monomer used in the polymerization step is 100%, emulsifier is added from time when polymerization progresses and Z % of the monomer converts by reaching the polymerization completion conversion; and X, Y and Z satisfy following relationship, 1
