摘要： A dip-molded article includes an external molded layer and internal molded layer. The external molded layer includes a content of an ethylenically unsaturated nitrile-based monomer-derived repeating unit is 35 wt % to 60 wt %, and the internal molded layer in which a content of an ethylenically unsaturated nitrile-based monomer-derived repeating unit is 10 wt % to 28 wt %.

摘要： A latex composition for dip molding includes a carboxylic acid-modified nitrile-based copolymer latex and a cholate-based emulsifier, wherein the cholate-based emulsifier is included in an amount of 0.02 to 3 parts by weight based on a solid content with respect to a solid content of 100 parts by weight of the carboxylic acid-modified nitrile-based copolymer latex. A method of preparing the latex composition for dip molding and a molded article produced using the same are also provided.
