<p>A dip-forming composition comprising a conjugated diene rubber latex prepared by copolymerizing 30-90 wt.% of a conjugated diene monomer, 0.1-20 wt.% of an ethylenically unsaturated acid monomer and 0-69.9 wt.% of other copolymerizable ethylenically unsaturated monomer, wherein a copolymer constituting the conjugated diene rubber latex exhibits a content insoluble in methyl ethyl ketone of not larger than 30 wt.% at a latex pH value of 10, and the dip-forming composition has a pH value of at least 8.5 and is substantially free from a sulfur-containing vulcanizer, a vulcanization accelerator for the sulfur-containing vulcanizer, and zinc oxide. A dip-formed article made therefrom, which has been crosslinked with a water-soluble polyvalent metal salt used as a coagulant for latex, has an extremely reduced number of pinholes, good softness to touch, high tensile strength and high fatigue resistance to repeated use.</p> |
