Title (EN) POLYMER PRODUCTS
(FR) PRODUITS POLYMERES
Abstract:
(EN) A specified porosity porous polymer product is made by precipitating polymer from a solution which contains a suspended porosifier under conditions in which the precipitate forms a solid which is rendered porous by dissolving the porosifier, and controlling the porosity by including in the solution a specific amount of a porosity controlling substance other than said porosifier. The substance may be a surfactant. The polymer product is useful as a vascular prosthesis.
(FR) Un produit polymère poreux à porosité spécifiée est obtenu lorsqu'on précipite un polymère à partir d'une solution qui contient un agent de porosité suspendu, dans des conditions où le précipité forme un solide qui devient poreux lorsque l'agent de porosité est dissous, la porosité étant régulée lorsqu'on inclut dans la solution une quantité spécifique d'une substance de régulation de porosité autre que ledit agent de porosité. La substance peut être un agent tensioactif. Le produit polymère est utile comme prothèse vasculaire.
