Abstract: 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.

Abstract: A method of making a polybenzimidazole (PBI) includes the steps of: reacting, in a solution, an organic compound having at least 2 amino groups with an organic aldehyde adduct, the reactants comprise at least 8% by weight of the solution. A solvent of the solution may be selected from the group of: N,N-dimethylacetamide (DMAc), N,N-dimethylformamide (DMF), dimethylsulfoxide (DMSO), N-methyl-2-pyrrolidone (NMP), tetramethylene sulfone, and combinations thereof. The organic aldehyde adduct may be an organic aldehyde bisulfite adduct. The organic aldehyde portion of the organic aldehyde adduct being aliphatic, alicyclic, aromatic, heterocyclic, or heteroaromatic aldehyde or mixtures thereof. The polybenzimidazole may have an intrinsic viscosity of at least 0.40 dl/g.
