    摘要： An amphoteric water-in-oil self-inverting polymer emulsion is prepared which contains a copolymer of (1) a nonionic vinyl monomer and (2) an amphoteric vinyl monomer or a terpolymer of (1) a nonionic vinyl monomer, (2) an anionic vinyl monomer and (3) a cationic vinyl monomer in the aqueous phase, a hydrocarbon oil for the oil phase, a water-in-oil emulsifying agent and an inverting surfactant. An example of a copolymer is a copolymer of (1) a nonionic vinyl monomer such as acrylamide or methacrylamide and (2) an amphoteric vinyl monomer such as a reaction product of dimethylaminoethyl methacrylate and monochloroacetic acid. An example of a terpolymer is a terpolymer of (1) a nonionic vinyl monomer such as acrylamide or methacrylamide, (2) an anionic vinyl monomer such as sodium acrylate and (3) a cationic vinyl monomer such as a triethyl ammonium ethyl methacrylate methosulfate salt. The emulsion is useful in papermaking, treatment of sewage and industrial wastes, drilling muds and secondary and tertiary recovery of petroleum by water flooding.

    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.
