  • Patent number: 8017685
    Abstract: Provided is an aqueous polyurethane emulsion composition having a urethane-urea bond, which is obtained by reacting a polyisocyanate, a polyester polyol and an ionic compound to prepare a polyurethane prepolymer, neutralizing it with an alkali or trialkylamine, dispersing it in water and reacting it with an amine, which is a chain extender. Polyurethane gloves manufactured with the aqueous polyurethane emulsion composition of the present invention have superior antistatic property, which is maintained even after washing, and wearing comfort similar to that of gloves made of natural latex and do not cause allergic reactions.
