  • Patent number: 7511116
    Abstract: A technique is described for the preparation of polymers according to a process in which the starting compound of formula (I) is polymerized in the presence of a base in an organic solvent. No end chain controlling agents are required during the polymerisation to obtain soluble precursor polymers. The precursor polymer such obtained comprises structural units of the formula (II). In a next step, the precursor polymer (II) is subjected to a conversion reaction towards a soluble or insoluble conjugated polymer by thermal treatment. The arylene or heteroarylene polymer comprises structural units of the formula III. In this process the dithiocarbamate group acts as a leaving group and permits the formation of a precursor polymer of structural formula (II), which has an average molecular weight from 5000 to 1000000 Dalton and is soluble in common organic solvents. The precursor polymer with structural units of formula (II) is thermally converted to the conjugated polymer with structural formula (III).

The membranes formed from the sulfonated polymers exhibit improved properties over that of Nafion®. A heteropoly acid may be added to the sulfonated polymer to form a nanocomposite membrane in which the heteropoly acid is highly dispersed. The addition of a heteropoly acid to the sulfonated polymer increases the thermal stability of the membrane, enhances the conductivity above 100° C., and reduces the water uptake of the membrane.

  • Publication number: 20080114149
    Abstract: The invention relates generally to polymers derived from monomers having aromatic superacidic functional groups. The superacidic functional groups comprise fluorinated sulfonate moieties. Polymers provided by the present invention include polyethers, polyesters, polycarbonates, polyestercarbonates, polyetherketones, and polyethersulfones among others. The polymers provided by the present invention include block and random copolymers. In one embodiment, the present invention provides a polyetherketone-polyethersulfone block copolymer comprising superacidic functional groups. Polymers comprising superacidic functional groups are useful materials in membrane applications. The superacidic functional groups present in the new polymer compositions impart excellent proton conductivities. In one embodiment, the present invention provides polymers useful as materials for polymer electrolyte fuel cell membranes.

  • Patent number: 7361729
    Abstract: Sulfonated polymers are made by the direct polymerization of a sulfonated monomer to form the sulfonated polymers. The types of sulfonated polymers may include polysulfones or polyimides. The sulfonated polymers can be formed into membranes that may be used in proton exchange membrane fuel cells or as ion exchange membranes. The membranes formed from the sulfonated polymers exhibit improved properties over that of Nafion®. A heteropoly acid may be added to the sulfonated polymer to form a nanocomposite membrane in which the heteropoly acid is highly dispersed. The addition of a heteropoly acid to the sulfonated polymer increases the thermal stability of the membrane, enhances the conductivity above 100° C., and reduces the water uptake of the membrane.
