Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A latex composition for dip molding, comprising: a carboxylic acid-modified nitrile-based copolymer latex; and a cholate-based emulsifier, wherein the cholate-based emulsifier is included in an amount of 0.5 to 3 parts by weight with respect to a solid content of 100 parts by weight of the carboxylic acid-modified nitrile-based copolymer latex. 2. The latex composition for dip molding of claim 1 , wherein the cholate-based emulsifier is one or more selected from the group consisting of cholic acid, glycocholic acid, taurocholic acid, deoxycholic acid, chenodeoxycholic acid, glycochenodeoxycholic acid, taurochenodeoxycholic acid, and lithocholic acid. 3. The latex composition for dip molding of claim 1 , wherein the cholate-based emulsifier is one or more salts selected from the group consisting of cholate, glycocholate, taurocholate, deoxycholate, chenodeoxycholate, glycochenodeoxycholate, taurochenodeoxycholate, and lithocholate. 4. The latex composition for dip molding of claim 1 , wherein the cholate-based emulsifier is sodium cholate. 5. The latex composition for dip molding of claim 1 , wherein the cholate-based emulsifier is included in an amount of 0.5 to 1.5 parts by weight with respect to the solid content of 100 parts by weight of the carboxylic acid-modified nitrile-based copolymer latex. 6. A method of preparing the latex composition for dip molding of claim 1 , the method comprising: preparing a carboxylic acid-modified nitrile-based copolymer latex; and mixing the prepared carboxylic acid-modified nitrile-based copolymer latex and a cholate-based emulsifier with each other, wherein in the mixing, the cholate-based emulsifier is mixed in an amount of 0.5 to 3 parts by weight with respect to a solid content of 100 parts by weight of the carboxylic acid-modified nitrile-based copolymer latex. 7. The method of claim 6 , wherein the cholate-based emulsifier is one or more selected from the group consisting of cholic acid, glycocholic acid, taurocholic acid, deoxycholic acid, chenodeoxycholic acid, glycochenodeoxycholic acid, taurochenodeoxycholic acid, lithocholic acid, and salts thereof. 8. A molded article comprising a layer derived from the latex composition for dip molding of claim 1 . 9. The latex composition of claim 1 , wherein the cholate-based emulsifier suppresses coagulation in the latex composition.
