Patent

CA 2248003

The invention is directed to a process for producing a porous polymer comprising the steps of: (1) dispersing a porogen in a continuous monomer component phase wherein said continuous monomer component phase comprises at least one monomer having at least one perfluoropolyether unit and wherein said porogen is an optionally substituted poly(alkylene)glycol; (2) thereafter polymerising the continuous monomer phase; and (3) removing the porogen from the porous polymer.

L'invention porte sur un procédé de fabrication d'un polymère poreux comportant les étapes suivantes: (1) dispersion d'un porogène dans une phase continue de composant monomère comprenant au moins un monomère présentant au moins une unité de perfluoropolyéther, ledit porogène étant un poly(alkylène)glycol éventuellement substitué; (2) polymérisation de la phase continue de monomère; et (3) élimination du porogène du polymère poreux.
