  • Patent number: 7582713
    Abstract: A thickened ion exchange polymer dispersion is obtained by applying ultrasonic vibration or a shearing force to an ion exchange polymer dispersion having a fluorinated polymer having sulfonic acid groups as an ion exchange polymer uniformly dispersed in a dispersion medium so that the viscosity of the dispersion at 25° C. at a shear rate of 10 (1/s) increases 2-2000 times in a thickening step. When formed into a membrane, the dispersion can forms an ion exchange membrane having a uniform and small thickness, high strength, which is free from cracking and shows constant swelling in water and steam. Further, a layer formed by applying a coating solution containing this dispersion and a catalyst powder comprising catalyst metal particles and a carbon support loaded with the catalyst metal particles to a substrate can be used to prepare a membrane-electrode assembly as a catalyst layer for at least one of the cathode and the anode by providing the catalyst layer adjacently to an ion exchange membrane.

    Abstract: A process of synthesizing hyperbranched polytriazoles, linear and hyperbranched poly(aroyltriazoles) by Huisgen 1,3-dipolar cycloaddition. The polytriazoles were prepared by A2+B3 method to avoid self-polymerization during monomer preparation and storage. The polymers are light emissive and can be crosslinked to generate well-resolution photopatterns upon UV irradiation. White light emission patterns were observed with fluorescence microscopy. The high molecular weight poly(aroyltriazoles) (up to 26000 Da) are prepared in high yields (up to 92.0%) and with high regioselectivity (the ratio of 1,4- and 1,5-disubstituted 1,2,3-triazole is equal or larger than 9:1). The polycyclomerization is not moisture or oxygen sensitive and therefore, no special precautions are necessary before and during the reaction. All the polymers are processible, easily film-forming, and curable into thermosets by heat or irradiation. The hyperbranched polymers can act as fluorescent adhesive materials with large tensile strength.

  • Patent number: 7064166
    Abstract: The present invention relates to a polymerization process for the control of the microstructure of polymers and to novel copolymers. An embodiment of the present invention relates a process of polymerizing first and second monomers in the presence of a complex comprising at least one of the monomers. The presence of the complex modifies the relative reactivity, or cross propagation rate constants, of the monomers in copolymerization reactions. Embodiments of the present invention allow the synthesis of polymers with novel stereochemistry and monomer sequence distribution, for example, but not limited to, copolymers with at least one segment of alternating monomers, a controlled molecular weight and narrow molecular weight distribution, or a segment of high concentration of the first monomer.

  • Patent number: 6924147
    Abstract: A polymeric food spoilage sensor comprises a polymer containing a polyazamacrocyclic transition metal complex. The complex selectively binds biogenic amines, such as cadaverine, putrescine and histamine, which are released by food spoilage microorganisms. The polymer undergoes a detectable color change upon exposure to biogenic amine, thus indicating that food spoilage has probably occurred. In one embodiment, the polymer is molecularly imprinted with the biogenic amine to impart selective binding affinity. The polymer is easily incorporated in common food containers and can be employed in fiber optic detection devices.
