Patent

CA 2285329

The invention is directed to a process for preparing porous polymer materials by a combination of gas foaming and particulate leaching steps. The invention is also directed to porous polymer material prepared by the process, particularly having a characteristic interconnected pore structure, and to methods for using such porous polymer material, particularly for tissue engineering.

L'invention a trait à un procédé de préparation de matériaux polymères poreux par combinaison d'étapes faisant intervenir un moussage au gaz et une lixiviation de particules. L'invention concerne également un matériau polymère poreux produit grâce à ce procédé, et pourvu, notamment, d'une structure caractéristique de pores interconnectés. Elle porte, en outre, sur des techniques d'utilisation de ce matériau polymère poreux, notamment dans le domaine des applications techniques du tissu.
