Abstract
Patente de Invenção: "FILME PARA USO MéDICO, CONSISTINDO EM POLìMEROS EM BLOCO LINEARES DE POLIURETANO E PROCESSO PARA A PRODUçãO DE TAL FILME". A presente invenção refere-se a um filme para uso médico consistindo em polímeros em bloco lineares de poliuretano uréia contendo grupos éster hidrolisáveis. Estes grupos éster devem ser espaçados um do outro na cadeia de carbono de modo que em sua hidrólise sejam formados fragmentos tão pequenos que possam ser eliminados de um corpo de mamífero incluindo seres humanos. O filme é caracterizado pelo fato de ser poroso com tamanho médio de poros de até 600 <109>m. A invenção também inclui um procedimento para a produção do filme no qual uma solução de polímeros formadores de filme com concentração de 5-30% é aplicada como camada fina em uma superfície após o que o solvente é evaporado e/ou a camada é tratada com um agente de precipitação de polímero.
