9 Claims

1. A carboxylic acid-modified nitrile-based copolymer latex composition comprising:

a carboxylic acid-modified nitrile-based copolymer, and

a coagulum,

wherein the carboxylic acid-modified nitrile-based copolymer includes a conjugated diene-based monomer-derived repeating unit, an ethylenically unsaturated nitrile-based monomer-derived repeating unit, an ethylenically unsaturated acid monomer-derived repeating unit, and a 2-hydroxyethyl methacrylate monomer-derived repeating unit in an amount 1.5 wt % to 6 wt % relative to a total weight of the carboxylic acid-modified nitrile-based copolymer, and

wherein the coagulum is included an amount of less than 1 wt % relative to a total weight of the latex composition.
