20130261239 | PROCESS FOR FORMING AN ARAMID COPOLYMER - The invention concerns processes for forming a polymer comprising residues of 2-(4-amino phenyl)-5(6) amino phenyl benzimidazole (DAPBI), paraphenylene diamine (PPD), and terephthaloyl dichloride, comprising the steps of: (a) forming a solution of oligomers having amine end groups from two moles of DAPBI and one mole of terephthaloyl dichloride in a solvent system comprising an organic solvent and an inorganic salt; (b) adding PPD to the solution of oligomers; and (c) adding additional terephthaloyl dichloride to form a polymer. | 10-03-2013 |
20130345350 | POLYMER COMPOSITIONS, POLYMER FILMS, AND METHODS FOR FORMING SAME - Stable, high performance polymer compositions including polybenzimidazole (PBI) and a melamine-formaldehyde polymer, such as methylated, poly(melamine-co-formaldehyde), for forming structures such as films, fibers and bulky structures. The polymer compositions may be formed by combining polybenzimidazole with the melamine-formaldehyde polymer to form a precursor. The polybenzimidazole may be reacted and/or intertwined with the melamine-formaldehyde polymer to form the polymer composition. For example, a stable, free-standing film having a thickness of, for example, between about 5 μm and about 30 μm may be formed from the polymer composition. Such films may be used as gas separation membranes and may be submerged into water for extended periods without crazing and cracking. The polymer composition may also be used as a coating on substrates, such as metal and ceramics, or may be used for spinning fibers. Precursors for forming such polymer compositions are also disclosed. | 12-26-2013 |
