| titleOfInvention | MEDICAL USE FOIL CONSISTING OF BLOCK POLYURETHANE POLYMERS AND PROCEDURE FOR MANUFACTURING SUCH FOIL |
| abstract | The present invention relates to a film for medical use consisting of linear block polymers of polyurethane urea containing esters that can be hydrolyzed. These ester groups are at such a distance from each other on the carbon sequence that during their hydrolysis such small fragments are formed that they can be excreted from the human body or the body of a mammal. The foil is characterized by the fact that it is porous with an average pore size of up to 600 Vµm. The invention also encompasses a process for making a film according to which the film-forming polymers with a concentration of 5-30% are applied in a thin layer to a surface, after which the solvent is evaporated and / or the layer is treated with a polymer deposition agent. invention concerns a film for medical use consisting of linear block polymers of polyurethane urea containing hydrolysable ester groups. These ester groups must be so spaced from each other on the carbon chain that on their hydrolysis such small fragments are formed that they can be secreted from a human body or that of a mammal. The film is characterized in that it is porous with an average pore size of up to 600 Vµm. The invention also includes a procedure for the production of the film in which a solution of the film-forming polymers with a concentration of 5-30% is applied as a thin layer on a surface after which the solvent is evaporated and / or the layer is treated with a polymer-precipitating agent. |
