Interpolymers of unsaturated carboxylic acids and unsaturated sulfur acids

The present invention relates to superabsorbent cross-linked polymers for watery liquids, which are built-up of partially neutralized monomers having monoethylenlcally unsaturated acid groups, optionally further monomers copolymerizable therewith, as well as polymers optionally suitable as graft basis, and which can be manufactured by using a cross-linker/monomer combination of

Biodegradable copolymers, methods of producing them and their use

A process for the quaternization of triethanolamine fatty acid esters and imidazolinamides with customary quaternizing agents in a reaction medium containing alkoxylated naturally occurring fats or oils, or mixtures thereof with free fatty acids, monoglycerides and/or diglycerides in the substantial absence of 2-propanol, and the use of the resulting reaction mixtures as the active components in laundry softener compositions.

Antiviral agent

The present invention relates to a process to improve the organoleptic behavior and the physical characteristics of leather by the use of aqueous solutions of copolymers of 90 to 20%-wt acrylic acid or methyacrylic acid, as well as 10 to 80%-wt of a monomer of the formula ##STR1## wherein R.sub.1 is hydrogen or methyl; R.sub.2 and R.sub.3, which are equal or different, are methyl or ethyl; x stands for an optionally branched alkylene radical with 1 to 5 carbon atoms; the amine nitrogen is optionally neutralized or quaternized; and the molecular weight of the copolymer, measured at a pH of 8.0, is less than 100,000. The concentration of the copolymer in the aqueous solution is 0.02 to 10%-wt, relative to the shaved weight of the leather.

Acrylic copolymers for re-tanning

The present invention relates to a process for the production of derivatives of natural fats and oils that is characterized in that the fats that are solid at room temperature or which contain solid fractions, mixtures of these with free fatty acids, mono- and/or diglycerides are oxyalkylated at elevated temperatures in the presence of basic catalysts having at least one 1,2-epoxide and the conversion products so obtained, optionally, after epoxidization are sulphonated in a manner known per se. The products are particularly suitable for use as leather dubbing agents.

The present invention relates to a process to improve the organoleptic behaviour and the physical characteristics of leather by the use of aqueous solutions of copolymers of 90 to 20%-wt acrylic acid or methyacrylic acid, as well as 10 to 80%-wt of a monomer of the formula ##STR1## wherein R.sub.1 is hydrogen or methyl; R.sub.2 and R.sub.3, which are equal or different, are methyl or ethyl; x stands for an optionally branched alkylene radical with 1 to 5 carbon atoms; the amine nitrogen is optionally neutralized or quaternized; and the molecular weight of the copolymer, measured at a pH of 8.0, is less than 100,000. The concentration of the copolymer in the aqueous solution is 0.02 to 10%-wt, relative to the shaved weight of the leather.

Retanning process

The present invention relates to a process for the production of textiles that are coated with polyurethane, in which the material that is to be coated is coated with two oppositely charged aqueous ionic dispersions of polyurethanes that contain no free isocyanate groups and contain covalently bonded, solubility-enhancing ionic groups, dried and optionally waterproofed. Cationic and anionic polyurethane dispersions are preferred in a weight ratio of 1:1, and are applied to the textile material in a two-coat technique, wet-on-wet. In addition, the invention relates to textile material produced in this way, with improved waterproof qualities and the use of such textiles for the production of breathable, water- and wind resistant clothing, industrial textiles, and leather substitutes, all of which are permeable to water vapour.

Process for the production of polyurethane-coated textile surfaces,

A process for the finish dressing of leathers dressed by a mineral or a combined method, by treatment with an aqueous solution of water soluble polymer dressing substances that are polymers of unsaturated monomers that contain sulfonic groups. These polymers contain, if necessary, additional basic units that do not affect the water solubility, these being derived from the comonomers that can be copolymerized with the monomers that contain the sulfonic groups and which do not contain phosphorus.

Process for finish dressing minerally dressed leathers or those dressed

The invention relates to a process for improving the lightfastness of conventionally dyed leathers by treating the leathers before, during or after fatting with alkane and/or chloroalkane sulfonamides in amounts of about 0.1 to 8 weight percent, based on the shaved weight of the leather. Used as alkane sulfonamides and chloroalkane sulfonamides are preferably products with a chain length of about 10 to 35 carbon atoms and a chlorine content of about 10 to 40%. The alkane and/or chloroalkane sulfonamides are advantageously used in aqueous solution or in stable emulsion. A substantial improvement in lightfastness is obtained regardless of the type of the dye, tanning agent, fatting agent or other leather treating agent used.
