摘要： Disclosed is a carboxylic acid-modified nitrile-based copolymer latex composition, including 0.1-10 parts by weight of a reactive emulsifier based on 100 parts by weight of a monomer mixture, wherein the monomer mixture includes 40-88 wt % of a conjugated diene-based monomer, 10-50 wt % of an ethylenically unsaturated nitrile monomer and 0.1-10 wt % of an ethylenically unsaturated acid monomer. Also disclosed are a method of preparing the carboxylic acid-modified nitrile-based copolymer latex composition and a latex composition for dip molding including the same. The carboxylic acid-modified nitrile-based copolymer latex composition reduces generation of foam through the use of a reactive emulsifier different from the conventional adsorption/desorption type emulsifier, thereby preventing degradation of the quality of latex caused by foam. In addition, the carboxylic acid-modified nitrile-based copolymer latex composition avoids a need for introducing a defoaming agent for removing foam or maturation process.

摘要： Provided is a latex composition for dip forming which includes 100 parts by weight of a nitrile-based hybrid latex including a first latex and a second latex which have different glass transition temperatures, and 2 parts by weight to 8 parts by weight of an ion-conductive polymer having a weight-average molecular weight of 400 to 1,000. The latex composition for dip forming has excellent low-temperature stability and a dip-formed article prepared using the composition has excellent tensile strength and elongation. Since wearing comfort is improved due to a decrease in modulus, the dip-formed article may be suitable for industries requiring such properties.
