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.

Abstract: The current invention relates to a composition for the preparation of thermoplastic polyurethane elastomer for use in a powder slush molding process. The composition for the preparation of thermoplastic polyurethane elastomer includes a polymer consisting of isocyanate, a chain-extension agent and polyol, and montan wax. When the thermoplastic polyurethane elastomer prepared using the composition of the current invention is used in a powder slush molding process, a molded end product is easily released at a powder slush molding process, and molding energy is lowered by lowing a process temperature, thereby shortening a process cycle time, and also, the decreased incidence of a blooming phenomenon and of pin holes results in improved flatness of the molded product. The molding composition of this invention is suitable for manufacturing skin materials of automobile instrument panels.
