To provide a method for removing and recovering unreacted monomers from a vinylidene chloride resin slurry.

This method for removing the unreacted monomers from the vinylidene chloride resin slurry comprises keeping an aqueous medium in the vinylidene chloride resin slurry containing the unreacted monomers and obtained by polymerization in the aqueous medium in a boiling state at ≤80°C temperature under a reduced pressure and vaporizing the unreacted monomers. The method for recovering the unreacted monomers from the vinylidene chloride resin slurry comprises cooling the removed unreacted monomer component, separating water, then further cooling the unreacted monomer component, liquefying the gaseous unreacted monomers and recovering the unreacted monomers.
