Abstract

Película para uso médico que consiste de polímeros lineales de bloque de poliuretano urea que contiene grupos éster hidrolizables. Estos grupos éster debenestar esparcidos uno de otro de tal manera en la cadena de carbono que al ser hidrolizados sef orman fragmentos tan pequenos que pueden ser secretados de uncuerpo humano o del cuerpo de un mamífero. La película se caracteriza porque la misma es porosa con un tamano medio de poro de hasta 600 micrones.Procedimiento para producir dichapelícula, por el cual una solucion de los polímeros que forman la película con una concentracion del 5-30% es aplicada en unacapa delgada sobre una superficie, después de lo cual el solvente es evaporado y/o la capa es tratada con un agenteprecipitador de po límero.
