A method of preparing the latex composition, and a dip-molded article produced using the latex composition are also provided.
Claims16
A latex composition for dip molding, comprising:
- a carboxylic acid-modified nitrile-based copolymer latex;
- and
- a thickener,
- wherein the thickener has an associative part and a non-associative part,
- the associative part has one or more hydrophobic groups selected from the group consisting of an alkyl group, aryl group, and arylalkyl group having 6 to 13 carbon atoms, and
- the non-associative part has a linear ether group having 1,000 or fewer carbon atoms.
3 more elements
