Abstract

See full text

A carboxylic acid-modified nitrile-based copolymer latex includes a carboxylic acid-modified nitrile-based copolymer including: 65.5 wt % to 82.5 wt % of a conjugated diene-based monomer-derived unit, 15 wt % to 30 wt % of an ethylenic unsaturated nitrile-based monomer-derived unit, and 2.5 wt % to 4.5 wt % of an ethylenic unsaturated acid monomer-derived unit, wherein the carboxylic acid-modified nitrile-based copolymer latex satisfies General Formula 1:

description='In-line Formulae' end='lead'1.0 mm2/s≤CV0≤3.0 mm2/s  [General Formula 1]description='In-line Formulae' end='tail'

    wherein CV0 represents a capillary viscosity of the carboxylic acid-modified nitrile-based copolymer latex which is measured in a swollen state in a methyl ethyl ketone solvent.
