    摘要: An anion exchange polymer has an ionomer structure containing poly(phenylene) compound integrated with functionalized poly(fluorene). The anion conducting co-polymer includes a poly(fluorene) compound and a poly(phenylene) compound covalently bonded together. The poly(fluorene) compound has a 9H-fluorene structure that is a polycyclic aromatic hydrocarbon having a center ring with five carbon atoms, and a benzene ring on each of opposing sides of said center ring. The poly(phenylene) compound is covalently bonded to each of the pair of benzene rings of the poly(fluorene) compound. A pair of sidechains extends from the center ring of the poly(fluorene) compound to a respective terminal group. The terminal groups are configured on sidechains of the poly(fluorene) compound and can be converted into functional groups such as quaternary ammonium or n-methyl piperidine functional groups. The anion exchange polymer may include a porous scaffold support.

    摘要: Ways of making electrodes and electrodes produced thereby are provided (100). Dry blending of a powder mixture including a catalyst (105), an ionomer (110), and a polyether (115) forms a blended mixture (135), which can be comminuted (140) to obtain a desired particle size. A slurry of the blended mixture is formed (145) with an aqueous medium and the slurry is coated (150) onto a substrate to form a coated substrate. The coating can be transferred to another substrate or material for use as an electrode and/or the substrate of the coated substrate can form part of a structure, such as a membrane electrode assembly for use in a fuel cell.

    摘要: Olefin polymers are produced having a controlled amount of xylene soluble content. For example, polypropylene polymers can be produced having a relatively high xylene soluble content. The polymers are produced using particular external electron donors. The polymers can be produced without using a silicon-containing external electron donor. The process has been found to produce not only polymers with relatively high xylene soluble content but with less fines and a narrow particle size distribution
