  • Publication number: 20110077358
    Abstract: A functionalized polymer is disclosed that comprises the reaction product of a polymer having one or more pendant reactive functional groups and a color changing indictor having a co-reactive functional group. The co-reactive functional group of the color changing is able to react with the reactive functional group of the polymer to form a covalent bond. Therefore, the color changing indicator is pendant from the polymer. The color changing indicator maintains its ability to produce a visually discernable color change in the presence of an associated stimulus.

  • Patent number: 7915351
    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.

  • Publication number: 20110040045
    Abstract: The embodiments of the present disclosure present systems and methods for the reversible solubilization of (aryl ether ketones) (PAEKs). A thioacetalization process is employed to modify the PAEKs into poly (aryl ether thioacetals) which, unlike PAEKs, are substantially soluble in common solvents. This modification allowing selected analysis techniques to be more easily performed on PAEKs1 such as gel permeation chromatography. The thioacetalization may be reversed through a deprotection reaction to recover the original PAEK without substantial degradation, allowing for non-destructive characterization of the PAEK. Advantageously, the thioacetalization process is generally applicable to a broad range of PAEKs, unlike presently known methods of solubilizing PAEKs. Solubilization of PAEKs further expands the utility of the PAEKs, opening up additional routes to chemical modification of PAEKs, as well as allowing for the possibility of processing PAEKs from solution.

The MMMs are in the form of symmetric dense film, thin-film composite (TFC), asymmetric flat sheet or asymmetric hollow fiber. These MMMs have good flexibility and high mechanical strength, and exhibit high carbon dioxide/methane (CO2/CH4) selectivity and high CO2 permeance for CO2/CH4 separation. The MMMs are suitable for a variety of liquid, gas, and vapor separations.

  • Patent number: 7541420
    Abstract: A method for preparing a molded article includes the steps of (a) obtaining a polycarbonate resin and (b) molding the polycarbonate resin. The polycarbonate resin is made by a transesterification reaction using an activated diaryl carbonate such that the polycarbonate is susceptible to the formation of internal ester linkages (IEL). The method occurs with the proviso that the polycarbonate resin, the molding conditions or both are selected to control the amount of IEL formed during the molding process to a level of less than 0.4 mol %.

    Abstract: A vinyl monomer is graft polymerized on an aromatic hydrocarbon-based polymer film substrate to introduce graft chains into the substrate and thereafter a functional monomer represented by the following formula and having sulfonic acid groups or functional groups capable of conversion to sulfonic acid groups is graft polymerized to introduce the sulfonic acid groups or the functional groups capable of conversion to sulfonic acid groups: where R is an aromatic ring or an aliphatic chain; X is (1) —OH, (2) —OLi, —ONa or —OK, (3) —F or —Cl, or (4) —OCnH2n+1 where n is an integer of 1 to 7. Since the graft chains obtained by graft polymerization of the vinyl monomer can also be utilized as scaffold polymers, the graft polymerizability of the functional monomer to the aromatic hydrocarbon-based polymer film substrate is sufficiently improved to enable the preparation of a polymer electrolyte membrane that excels not only in proton conductivity and mechanical strength but also in dimensional stability.
