Provided is a composition preventing tissue adhesion and a method for preparing the same, and, more particularly, a composition preventing tissue adhesion which further contains a drug selectively inhibiting inflammatory response and a method for preparing the composition, in which the composition is produced through a chemical reaction by adding a cross-linking agent to an aqueous solution which contains a block copolymer containing a polyethyleneoxide block having the ability to suppress tissue adhesion, and a polymer with 10,000 to 1,000,000 g/mol of molecular weight which can be mixed with the copolymer; the composition is characterized in that the difference of viscosity, absorbance of visible rays region, and stability between the upper and lower liquid layers are within 10% when centrifuging the composition; and also the method for preparing the composition enhances cross-linking homogenization and viscosity stability through simultaneous spraying and stirring methods without a reaction retardant.

Composition preventing tissue adhesion and preparation method thereof

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.
