摘要： Aqueous gels of water-soluble polymers and copolymers of extremely high molecular weight as measured by their intrinsic viscosities are prepared by the irradiation, under controlled conditions of concentration, radiation intensity, and total dose, of aqueous solutions of selected nitrogen-containing vinyl monomers separately, in admixture with each other or in admixture with non-nitrogenous vinyl monomers. The polymers may be recovered from the gels in coventional manner. The polymers and the gels are useful as flocculating and thickening agents in aqueous media.

摘要： Polymers formed by interpolymerization in an aqueous acidic system of acrylonitrile or methacrylonitrile with sulfonic acid monomers (particularly acrylamidoalkanesulfonic acids and their salts) are improved as to basic dye affinity by carrying out the polymerization in the presence of a minor amount of an amine salt, especially a nitrate or chloride of a mono- or di-(lower alkyl)amine.

摘要： Insoluble polymeric organotin hydrides of the formula: ##EQU1## wherein P represents an organic polymer backbone; R and R.sub.1 each represent a hydrogen atom, a lower alkyl group of 1 to 5 carbon atoms, an aryl group of 6 to 10 carbon atoms, or an alkaryl or aralkyl group of from 7 to 10 carbon atoms; and n is a positive number greater than 1 are disclosed. Such polymeric organotin hydrides are useful as reagents for reducing organic compounds such as organic halides, ketones, and aldehydes without the different problem of removing dissolved or dispersed tin impurities from the reduced compounds.

摘要： New polymers and copolymers containing silver and/or copper, useful e.g. in manufacturing dialysis and filtration membranes, ion exchangers, light sensitive layers, catalysts and hydrophilic coatings, are prepared from copolymers or polymer mixtures containing both nitrile groups and strong acidic groups, by bringing them in contact with monovalent silver or copper ions or with their mixtures. Silver and/or copper are attached to nitrile groups by secondary valences, thus forming complex compounds. The probable formulae of the complex groups are: --CN.Ag.sup.+ or perhaps --CN.Ag.sup.+.NC-- and --CN.Cu.sup.+ or perhaps --CN.Cu.sup.+.Cu.sup.+.NC-- , the complex cations forming polymeric salts with strong acidic groups of the same or of an adjoining macromolecule, to which all said nitrile and strongly acidic groups are attached as substituents.
