The polyelectrolytes used in practical glass-ionomers are polyaUcenoic acids, and two such substances are employed as the main polymer in these cements, namely the homopolymer poly(acrylic acid) and the 2 1 copolymer of acrylic acid and maleic acid. In addition, poly(vinyl phosphonic acid) has been studied as a potential cement former, but its practical use is restricted to a single brand, where it is used in a mixture with poly(acrylic acid) and effectively acts as a setting rate modifier. [Pg.110]

Polyelectrolytes may be polyacids, polybases, or polyampholytes. They dissociate into polyions and oppositely charged gegenions. Polyacids release protons on dissociation and become, then, polyanions. Poly(phosphoric acid), I, is an example of a polyacid with a dissociating group in the main chain examples of polyacids with the dissociating group as substituent to the main chain include poly(vinyl phosphonic acid), 11 poly(vinyl sulfuric acid), III poly(vinyl sulfonic acid), IV and poly(vinyl carboxylic acid) = poly-(acrylic acid), V, with the monomeric units... [Pg.40]

A commercial phosphoric acid doped PBI membrane, Celtec V by BASF Fuel Cells, tailored for DMFC is based in a blend of PBI and poly(vinyl phosphonic acid) (PVPA). The PVPA poly acid is immobilized in the PBI matrix by interpenetration, crosslinking and covalent bonding [201]. [Pg.135]

Complex polymer electrolytes based on poly(vinyl-phosphonic acid) and poly( 1 -vinyl-1,2,4-triazole) have been fabricated as membrane materials [96]. The presence of poly(l-vinyl-l,2,4-triazole) in the complex polymer electrolytes suppresses the formation of phos-phonic acid anhydrides up to 150 After humidification at a level of 50%, proton conductivities of 0.008-0.022 S cm at 100 °C are observed. [Pg.233]

Trisodium l-phosphono-2-phosphino ethane is used as an end-capper. This compound is also addressed as a telomeric adduct from vinyl phosphonic acid and sodium hypophosphite (12). [Pg.286]
