摘要:
A process for producing a solution blend of a polybenzimidazole (PBI) and a polyetherketoneketone (PEKK). The PBI is mixed with sulfuric acid at a temperature between 40° C. and 80° C. for 30 minutes to 2 hours to produce a PBI solution then cooled to room temperature to form a cooled PBI solution. Then PEKK is added to the cooled PBI solution to form a mixture and that mixture is stirred from 30 minutes to 2 hours at room temperature to form a stirred mixture. The stirred mixture is poured into an excess of water being stirred swiftly to form an aqueous mixture. The aqueous mixture is filtered to produce a blend. The blend is washed with water and dried. The resulting blend can yield a blend in all proportion from 1/99 PBI/PEKK to 99/1 PBI/PEKK.
