abstract |
The present invention relates to a method for producing a carboxylic acid-modified nitrile-based copolymer latex, wherein a monomer mixture containing a conjugated diene-based monomer, an ethylenically unsaturated nitrile-based monomer, and an ethylenically unsaturated acid monomer is prepared in the presence of a crosslinking agent including glyoxal. It provides a method for producing a carboxylic acid-modified nitrile-based copolymer latex comprising the step of emulsion polymerization under. |
