Title (EN) POROUS POLYBENZIMIDAZOLE RESIN AND METHOD OF MAKING SAME
(FR) RÉSINE POREUSE DE POLYBENZIMIDAZOLE ET SON PROCÉDÉ DE PRODUCTION
Abstract: front page image
(EN)A porous polybenzimidazole (PBI) particulate resin is disclosed. This resin is easily dissolved at ambient temperatures and pressures. The resin is made by: dissolving a virgin PBI resin in a highly polar solvent; precipitating the dissolved PBI in a bath; and drying the precipitated PBI, the dried precipitated PBI being porous. The porous PBI resin may be dissolved by: mixing a porous PBI resin with a highly polar solvent at ambient temperatures and pressures to form a solution.
(FR)L'invention concerne une résine particulaire poreuse de polybenzimidazole (PBI), qui se dissout facilement à températures et pressions ambiantes. La résine est produite par: dissolution d'une résine PBI vierge dans un solvant hautement polaire; précipitation du PBI dissous dans un bain; et séchage du PBI précipité, le PBI précipité séché étant poreux. La résine poreuse de PBI peut être dissoute par mélange d'une résine poreuse de PBI avec un solvant hautement polaire à températures et pressions ambiantes pour former une solution.
