摘要： A dip-forming composition which contains a weight average molecular weight 10,000 to 5,000,000 synthetic polyisoprene latex, a polycarboxylic acid and/or salt of a polycarboxylic acid, a sulfur-based vulcanizer, and a vulcanization accelerator is provided. According to the invention, a dip-forming composition which can suppress formation of coarse coagulum during aging and which can give a dip-formed article which is excellent in tensile strength and elongation even when the aging temperature is relatively low and the aging time is relatively short and, further, has excellent safety even when used in contact with the human body can be provided.

摘要： A dip-forming synthetic isoprene polymer latex contains a synthetic isoprene polymer which has been subjected to solution polymerization using an alkyllithium polymerization catalyst. A ratio between a mode diameter and a median diameter (mode diameter/median diameter) of a particle diameter of the latex is 0.8 or more. A Brookfield viscosity difference (V66−V56) between a Brookfield viscosity at a solid content concentration of 56% (V56) and a Brookfield viscosity at a solid content concentration of 66% (V66) is 200 mPa·s or less.
