摘要： There are provided a dip-molded product that has good resistance to organic solvents, good feeling, sufficient tensile strength, and high contact-state-sustaining performance, a dip-molding composition for forming the dip-molded product, and a dip-molding copolymer latex that can suitably be used for the dip-molding composition. The copolymer latex is a carboxylated acrylonitrile-butadiene copolymer latex that is produced by copolymerization of a monomer mixture of a specific composition comprising 1,3-butadiene, acrylonitrile and methacrylic acid, in which a part of the total amount of the acrylonitrile and a part of the total amount of the methacrylic acid are added to the polymerization reaction system at a specific time after the initiation of the polymerization, and the content of methyl ethyl ketone-insoluble components in the resulting polymer is in a specific range. The dip-molding composition comprises the latex, a vulcanizing agent and a vulcanization accelerator.

摘要： A dip-forming latex obtained by copolymerization of (a) 50-89.5 weight parts of a conjugated diene monomer, (b) 10-40 weight parts of an ethylenically unsaturated nitrile monomer, (c) 0.5-10 weight parts of an ethylenically unsaturated acid monomer and (d) 0-20 weight parts of other copolymerizable ethylenically unsaturated monomer (the total of these monomers is 100 weight parts), wherein the copolymerization is initiated with a monomer mixture comprising at least 80 wt. % of (a), at least 50 wt. % of (b), 10-90 wt. % of (c) and least 80 wt. % of (d), and thereafter, the remainders of monomers are added to a polymerization system to continue copolymerization. This latex gives a dip-formed article exhibiting good softness of touch, high tensile strength and good retention of close fittingness.
