Method for recovering unreacted α,β-ethylenically unsaturated nitrile monomer contained in carboxyl-containing nitrile rubber latex |
abstract |
The present invention provides a method for recovering unreacted α,β-ethylenically unsaturated nitrile monomers, which is for emulsion polymerization of monomer mixtures comprising α,β-ethylenically unsaturated nitrile monomers and carboxyl group-containing monomers The method for recovering the unreacted α,β-ethylenically unsaturated nitrile monomer contained in the obtained nitrile rubber latex includes the following steps: a step of adjusting the pH of the nitrile rubber latex to be 6.5 or more; A step of depressurizing the above-mentioned nitrile rubber latex adjusted to pH 6.5 or more under heating conditions; and a step of recovering components evaporated by the decompression under the above-mentioned heating conditions. |
