A film for medical use, consisting of linear block polymers of polyurethane and a method for the production of such a film |
| abstract |
The present 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 characterised in that it is porous with an average pore size of up to 600 νm. 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. |
