Abstract: This invention relates to copolymers of alpha-olefins and maleic anhydride reacted with amines in the presence of Lewis acids, preferably BF.sub.3 or a complex thereof; and to the use of these products as anti-static agents in organic liquids, preferably in hydrocarbons. The use of Lewis acid produces a unique reaction product which is superior as to fluidity and/or anti-static properties as compared to the corresponding product produced without Lewis acid. In addition, the use of Lewis acid promotes the rate of reaction thus reducing reaction time.
Abstract: A process for the dyeing of wool-containing fibre materials with anionic dyes, which process comprises dyeing these materials in the presence of an optionally etherified N-methylolurea compound which serves as a wool protective agent.
Abstract: Solid dye preparation containing at least one water-soluble dye, a lactam of the formula ##STR1## wherein x represents the numbers 3 to 6, and optionally further additives.
Abstract: A process for the low temperature removal of soil and/or stains from fabrics by immersing the fabrics in a peroxygen bleach bath containing as a peroxygen activator an aromatic sulfonyl azide of the formula:R--(SO.sub.2 N.sub.3).sub.nwherein R is an aromatic ring selected from the class consisting of phenyl, naphthyl and heterocyclic of 1 to 2 rings each containing 5 to 6 members of which 1 to 2 are nitrogen or sulfur atoms said aromatic ring optionally bearing 1 to 3 substituents selected from the class consisting of nitro, alkyl of 1 to 6 carbon atoms, lower fluorinated alkyl alkoxy of 1 to 6 carbon atoms, aliphatic carboxamido of 1 to 6 carbon atoms, benzamido and halogen and n is an integer of 1 to 2, it being provided that there are at least 5 carbon atoms per azide function.

Abstract: Polyester polymer is recovered from mixed collections of fibers in the form of fibers, filaments, yarns, or fabrics (including dyed or undyed fibers other than polyester fibers as well as dyed polyester fibers) and used in the production of new undyed fibers, by solvent stripping the dye from the polyester fibers without dissolving the fibers, and with additional solvent, selectively dissolving the polyester fibers in successive but functionally integrated steps; separating the dissolved fibers from an undissolved impurities and thereafter separating the residual dye-stripping solvent and the additional solvent from the polyester component without precipitiating the polyester component from solution by evaporating the solvent, preferably by atmospheric boiling and vacuum finishing of the molten solution.

Abstract: Stable bipolar membranes of high permselectivity and low potential drop are prepared using either an anion or cation preformed first layer upon which a second layer or coating of an ion exchange resin of the opposite charge carried in a matrix polymer is applied. The second layer may be suitably applied such as by casting as a slurry of the ion exchange resin in a solution or by laminating a layer comprising a dispersion of the resin in a solid or fused polymer. Optionally, the surface of the first layer may be treated to increase the resin concentration and/or bonding at the interface, such as by sanding, etching, etc.
