Abstract
(EN)

PROBLEM TO BE SOLVED: To provide a dip molded product excellent in a touch feeling and having excellent tensile strength, to provide a dip molding composition capable of giving the dip molded product, to provide a dip molding latex capable of being used for the dip molding composition, and to provide a method for producing the latex.

SOLUTION: This dip molding latex comprises the latex of a copolymer which is given by copolymerizing 100 pts.wt. of a monomer mixture comprising 65-84.5 pts.wt. of a conjugated diene monomer, 15-25 pts.wt. of an ethylenic unsaturated nitrile monomer, 0.5-10 pts.wt. of an ethylenic unsaturated acid monomer, and 0-19.5 pts.wt. of the other ethylenic unsaturated monomer capable of copolymerizing with the monomers, wherein the copolymer has a first glass transition temperature (Tg1) and a second glass transition temperature (Tg2), so that a difference between Tg1 and Tg2 is not more than 20C.
