Celazole®

POLYBENZIMIDAZOLES. These are heterocyclic polymers that have outstanding high thermal characteristics, the highest obtainable in commercial polymers. These materials also have superior ablative and hydrolytic stability as well as high compressive and dimensional stability. Polybenzimidazoles essentially arc unaffected by solvents, acids, and bases. They are marketed in stock shapes and as finished parts. The materials are not available in resin form Hoechst Celanese markets tile products under tile tradename Celazole, ... [Pg.1334]

PBl is today considered the most interesting basic polymer for preparation of acid-base membranes, especially if doped with phosphoric acid [24]. In Fig. 3.3 the scheme of the commercial PBl known as Celazole is shown. [Pg.82]

As already mentioned, the acid-base blend concept was applied to intermediate-T fuel cell membranes by Hasiotis et al. [31, 42]. The blend membranes were composed of PBI Celazol (poly(2,2 -/M-phenylene-5,5 -bibenzimidazole, m-PBl, named as Bl) and polysulfone Udel sulfonated in the bisphenol A section (named... [Pg.64]
