Abstract
(EN)
The present invention relates to a latex composition for dip molding. More specifically, the present invention provides a latex composition for dip molding, a manufacturing method therefor, and a molded article manufactured therefrom, the latex composition for dip molding comprising a carbonic acid-modified nitrile-based copolymer latex and a hydrophobically modified, alkali-soluble emulsion thickener, wherein the hydrophobically modified, alkali-soluble emulsion thickener comprises a copolymer containing an assembly part and a non-assembly part. The assembly part comprises a monomer-derived repeating unit, the monomer having as a substituent at least one first hydrophobic group selected from the group consisting of: alkyl, alkenyl, perfluoroalkyl, and carboxylyl which each have 8 to 15 carbon atoms; and aryl, arylalkyl, arylalkenyl, alicyclic alkyl, and polycyclic alkyl which each have 6 to 15 carbon atoms.
