    摘要： The present invention relates to a porous membrane containing cellulose fibers, wherein the cellulose fibers contain 5% by weight or more of cellulose fibers with a diameter of 1 μm or more, relative to the total weight of the cellulose, and the porous membrane has a tensile strength of 50 N·m/g or more, and/or has a tear strength of 0.40 kN/m or more. The porous membrane according to the present invention can provide a separator for electrochemical devices with superior properties, at a reasonable cost.

    摘要： ANION EXCHANGE MEMBRANES CAN BE PREPARED FROM CELLULOSE SHEET MATERIALS SUCH AS CELLOPHASE, PARCHMENT PAPER, OR KRAFT PAPER BY IMPREGNATING THE SHEET WITH POLYETHYLENEIMINE. THE MEMBRANE IS CROSS-LINKED AT A TEMPERATURE FROM 10 TO 50*C., WITH A RREAGENT SELECTED FROM THE GROUP OF MONALDEHYDES, DIALDEHYDES, REACTIVE METHOLYOL COMPOUNDS AND MIXTURES THEREOF. THE MEMBRANE IS THEN QUATERNIZED. IT IS PARTICULARLY SUITED FOR USE IN THE ELECTRODIALYTIC PURIFICATION OF SALINE WATER.

    摘要： Ion-exchange paper in which at least 10 per cent, based on the dry weight of pulp, of discrete, preferably pulverized, particles of one or more ion-exchange resins passing U.S. Standard sieve No. 50 are uniformly distributed (see Group VIII) can be used e.g. to remove acidic impurities from lubricating oils. Paper containing mixed particles of cation-and anion-exchange resins is particularly suitable for purifying water.ALSO:Ion-exchange paper in which at least 10 per cent, based on the dry weight of pulp, of discrete, preferably micropulverized, particles of one or more ion-exchange resins passing U.S. Standard Sieve No. 50 are uniformly distributed (see Group VIII), is used for wrapping and preserving foodstuffs, in filter tips and cartridges for cigarettes and tobacco pipes and in catamenial appliances. Anion-exchange and/or cation-exchange resins may be used. Suitable cation-exchange resins are the sulphonated copolymers of styrene and divinylbenzene and copolymers of methacrylic acid and divinylbenzene. The anion-exchange resin may be a copolymer of styrene and divinylbenzene having quaternary ammonium groups joined by means of methylene groups to the aromatic nuclei. Anion-exchange resins made by reacting diethylenetriamine with an insoluble copolymer of ethyl acrylate and divinylbenzene or by reacting trimethylamine with a chloromethylated copolymer of styrene and divinylbenzene may be used. Alum or sulphuric acid, fillers, dyes, pigments and wet-strength resins such as urea - formaldehyde and melamine - aldehyde resins may be incorporated in the paper pulp. The paper may be rendered greaseproof by parchmentizing.

    摘要： A highly dispersed solid non-porous insoluble and infusible urea-formaldehyde condensation polymer in the form of a fluffy white powder, said product having a specific surface area of more than 10 square meters per gram and an average particle size smaller than 5 microns. The product preferably essentially consists of approximately spherical microparticles having substantially uniform size and shape and shows a tendency to form loosely agglomerated structures. These solids are useful as rubber reinforcing agents and as paper pigmentary fillers.
