Abstract
Foreliggende oppfinnelse omhandler en film for medisinsk anvendelse som består av lineære blokkpolymerer av polyuretanurea som inneholder hydrolyserbare estergrupper. Disse estergruppene må ha et slikt mellomrom mellom seg på karbonkjeden at ved deres hydrolyse blir det dannet så små fragmenter at de kan bli utskilt fra kroppen til et menneske eller den til et pattedyr. Filmen er karakterisert ved at den er porøs med en gjennomsnittelig porestørrelse på opptil 600 |im. Oppfinnelsen inkluderer også en fremgangsmåte for fremstillingen av filmen, der en løsning av de filmdannende polymerene med en konsentrasjon på 5-30 % blir påført som et tynt lag på en overflate, hvoretter løsningsmidlet blir fordampet og/eller laget blir behandlet med et polymerpresipiterende agens.
