Abstract: A thermoplastic hot-melt adhesive based on a polymer blend of polyolefins is disclosed. An oligomer of an alpha-olefin with at least eight carbon atoms in the monomer and a molecular weight of the oligomer of up to 5,000, as well as other known additives, are added to the known mixture of a substantially amorphous poly-alpha-olefin and of a substantially crystalline poly-alpha-olefin. The impact strength, the viscosity and the flexibility at low temperatures are above all improved in this manner. These hot-melt adhesives are therefore suitable above all for gluing non-polar plastics in the automobile and electric industry.

Abstract: A process for removing printing inks from printed wastepaper in the presence of a deinking chemical is provided. In this process printed wastepaper is disintegrated to form a paper stock suspension and the detached printing ink particles are removed in known manner by flotation or washing in another stage. In this process, alkoxylates of blown oils are used as the deinking chemical. The deinking chemical is added during disintegration and/or before the flotation or washing step. Preferably, the printed wastepaper is disintegrated in the presence of 0.02 to 2% by weight and preferably 0.1 to 0.8% by weight, based on air-dry paper stock, of alkoxylates of blown oils. This deinking chemical also removed printing inks from paper circuit waters.

Abstract: A process for the production of carboxyfunctional polyurethane from dihydroxyfatty acids and/or dihydroxypolyfatty acids as isocyanate-reactive compounds bearing an ionizable group is provided. The dihydroxycarboxylic acids and/or dihydroxypolyfatty acids have no shielding molecular group near the carboxy group, more particularly not in the alpha-position to the carboxy group, and thus give particularly good results when used as a structural element for the production of polyurethanes. Also provided are polyurethanes and aqueous polyurethane dispersions produced using the dihydroxyfatty acids.

Abstract: A process has been discovered for making alkyl polyglycoside which comprises reacting a fatty alcohol having from about 8 to about 22 carbon atoms with a sugar, in the presence of an acid catalyst, to form a product of alkyl polyglycoside and excess fatty alcohol. The molar ratio of fatty alcohol to sugar, respectively, is at least 2:1. The excess fatty alcohol is then separated from the alkyl polyglycoside product. Once separated, the excess fatty alcohol is then reacted with a source of boric acid to form a mixture comprised of one or more borate esters of the fatty alcohol and inert compounds. The non-hydroxylic compounds are then separated from the borate esters. The substantially pure fatty alcohol is then returned to the beginning of the process for use in the formation of alkyl polyglycoside.

Abstract: The crude reaction products from the synthesis of alkyl glycosides are bleached by kneading the material substantially freed from the excess fatty alcohol and containing at most limited quantities of water with an oxidizing agent at such elevated temperatures that the reaction mixture lends itself to plastic processing. Temperatures of from about 50.degree. to 150.degree. C. are particularly suitable, although it is best to apply temperatures in the range from about 80.degree. to 100.degree. C. using aqueous hydrogen peroxide as the oxidizing agent. Bleaching is carried out under basic conditions, optionally by addition of an alkaline compound, such as for example 50% sodium hydroxide solution. The bleached product accumulates in the form of a solid. It is preferably mixed with typical compatible solids, more particularly typical constituents of detergents and cleaning preparations, to form a solid and preferably free-flowing alkyl glycoside compound.
