  • Patent number: 4795762
    Abstract: A new water-swellable composition of a gelling agent based on hydrolyzed homo- or copolymers of acrylonitrile and of an inert metal oxide was synthesized. In the process, 1 to 22% of the nitrile groups were saponified to amide groups and 99 to 78% to alkali-metal salts. The obtained composition had a spongy structure and was characterized by high values with regard to both swelling capacity and swelling rate. Therefore it is particularly suitable for diaper manufacture and for agricultural use.

  • Patent number: 4708985
    Abstract: The invention relates to a hydrophilic moulding compound of homopolyester and/or copolyester which contains 1 to 20 percent by weight of an alkaline and/or alkaline-earth salt of salt-forming polymer and/or copolymers from ethylenic unsaturated monomers as finely dispersed filling material, having in particualr a maximum particle size of 1 um, the salt-forming polymers being composed in particular of the following single monomers or mixtures thereof: vinyl-sulfonic acid, acrylamidoalkylene-sulfonic acid, sulfonated styrene, acrylic acid, methacrylic acid, maleic acid, fumaric acid, itaconic acid, crotonic acid, vinyl-phosphonic acid, monoalkyl ester of maleic acid, monoalkyl ester of fumaric acid.The invention also relates to a process according to which the salts are preferably added to the polycondensation mixture of the polyester starting materials before and/or during poly-condensation as a suspension in polyhydric alcohol.

  • Patent number: 4463157
    Abstract: Self-curing cationic amide-group-containing aminourea resins are disclosed, if necessary with urethane groupings, which are the reaction product of at least(A) a polyaminoamide which has been produced from(1) one or more predominantly higher fatty acids and one or more alkylene or polyalkylene-polyamines and/or(2) dimer fatty acids, if necessary in mixture with predominantly higher, substantially unsaturated fatty acids, and one or more alkylene- or polyalkylene-polyamines, and additionally partially contains cyclic amidine-groupings produced under splitting off of water and, if necessary, amino-groups blocked by ketimine,(B) a diisocyanate and, if necessary, of(C)(1) a primary and/or secondary allyl- or methallylamine and/or(2) one or more saturated primary and/or secondary aliphatic, cycloaliphatic, heterocyclic or aromatic amines and/or(3) an allyl- or methallyl-alcohol and/or(4) one or more cyclic or polycyclic alcohols, which are olefinically unsaturated in their cyclic or polyclicic ring systems, and/or

  • Patent number: 4437960
    Abstract: Method for the crosslinking of cathodically depositable coating agents, optionally containing pigment, dyestuff, filler, solvent, varnish adjuvant or additional crosslinking components, based upon a water-soluble or -dispersible nitrogen based cationic resin, at least partially present as salt, in which a cationic resin of molecular weight greater than 1000, containing 2 to 20 equivalents of double bonds per 1000 g, is contacted with sulfur and/or one or more sulfur-containing vulcanization acceleration. The coating mixture is then electrophoretically deposited upon an object, and hardened at temperatures above 120.degree. C. The resin may contain tertiary atoms of carbon, and also one or more sulfur-free vulcanization accelerators may be used.

  • Patent number: 4056400
    Abstract: A composition which consists essentially of a mixture of oligomeric and polymeric oxidation products of cellulose, hemicellulose and lignin containing carboxy, ether and hydroxy groups as obtained by the direct oxidation of a woody plant material, preferably in an aqueous suspension thereof, using alkali hypohalite in a one stage oxidation procedure or nitrogen dioxide, alkali periodate or lead tetraacetate followed by alkali chlorite or alkali hypochlorite in a two stage oxidation procedure. The resulting oxidation products as obtained by one of these specific processes are especially valuable as additives to a surface active detergent or cleaning agent.

  • Patent number: 3979451
    Abstract: A process for the production of thiophosgene by the reduction of trichloromethanesulfenyl chloride with hydrogen sulfide at an elevated temperature and in contact with silica gel, the molar ratio of the hydrogen sulfide to trichloromethanesulfenyl chloride being from 1.5:1 to 4:1.
