    Abstract: Described are polycondensation products obtained by condensing (a) butane-1,2,3,4-tetracarboxylic acid, optionally mixed with hydroxycarboxylic acids or other carboxylic acids, with (b) polyhydroxy compounds selected from the group comprising mono-, oligo- and polysaccharides, reduced mono- and oligosaccharides and their amino derivatives, oxidized mono-, oligo- and polysaccharides, alkyl polyglycosides, polyvinyl alcohols and oligoglycerins with more than 2 glycerin units, or mixtures thereof, plus, optionally, (c) up to 20 mole %, relative to component a, of alkylene glycols, polyalkylene glycols or monohydric C4-C20 alcohols, in the ratio, by weight, of a:b from 50:1 to 0.5:1, the condensation products produced having a K-value of 8 to 100 (determined by the H. Fikent method in a 2 % by wt. aqueous solution at 25 DEG C and pH 7 on the Na salts of the condensation products). The invention also concerns the use of the polycondensation products as additives to low-phosphate or phosphate-free washing or cleaning agents in amounts ranging from 0.1 to 30 % by wt. relative to the agent.

    Abstract: New polyglycerol ether carboxylates of formula shown are claimed. R = of formula (I) or (II), and up to 80% of the R gps. = H; X = H, alkali metal, NH4 and/or substd. NH4; and n = 1-10. (I) are prepd. by etherifying 20-100% of the OH gps. of cpds. of formula (III) by reaction with maleic and/or itaconic acid or anhydride, in aq. medium in presence of at least 30 mols% of alkaline earth metal ions, w.r.t. the dicarboxylic acid or anhydride, at pH 9-13 and 50-150 deg C. USE/ADVANTAGE - (I) are additives in phosphate-free or low-phosphate washing and cleaning compsns., in amt. of 0.1-20 wt.% (claimed). They can also be added to the last rinse, to give a soil-release effect. (I) have a synergistic effect with other components of washing compsns., inhibiting greying and reinforcing the action of other components. They are esp. useful in removing particulate dirt e.g. clay and are biodegradable.

    Abstract: Graft copolymers obtainable by free radical-initiated copolymerization of (A) a monomer mixture comprising (a) a monoethylenically unsaturated C4- to C8-dicarboxylic acid, or an anhydride, alkali metal salt or ammonium salt thereof, (b) a monoethylenically unsaturated C3- to C10-carboxylic acid, or an alkali metal salt or ammonium salt thereof, (c) if desired another monoethylenically unsaturated monomer which can be copolymerized with monomer (a) and (b), and (d) a monomer containing two or more ethylenically unsaturated, non-conjugated double bonds in the molecule, in the presence of (B) a monosaccharide, oligosaccharide, polysaccharide, oxidatively, hydrolytically or enzymatically degraded polysaccharide, oxidized, hydrolytically or enzymatically degraded polysaccharide, or chemically modified monosaccharide, oligosaccharide or polysaccharide, in the weight ratio (A):(B) of (95 to 20):(5 to 80), a process for the preparation of the graft copolymers, and detergents and cleaners containing the graft copolymers in amounts of from 0.1 to 20% by weight, are described.

    Abstract: A process is disclosed for preparing polymers with hydroxamic acid, hydroxamic acid ether and/or hydrazide groups in the side chain, by reacting (a) polymers which contain ester, amide, imide and/or acetal groups in the main chain and carboxyl, ester, imide, amide and/or anhydride groups and/or halogen as side chain, or a polysuccinimide with (b) hydroxylamine, hydroxylamine alkyl ethers with 1 to 18 C atoms in the alkyl group, N-monoalkylhydroxylamines with 1 to 18 C atoms in the alkyl group and/or in salts of said compounds and/or (c) hydrazine and/or hydrazine salts in an aqueous medium or alcohols at pH values of at least 7. Also disclosed is the use of the thus obtained modified polymers as additives to washing and cleaning agents, as complexing agents for alkaline earth and heavy metal ions, as pigment dispersants and as scale inhibitors.

    Abstract: The invention relates to a process for preparing copolymers from vinyl esters and monoethylenically unsaturated carboxylic acids by the radical copolymerisation of: (a) 20 to 80 mol % vinyl esters of aliphatic monocarboxylic acids having at least two carbon atoms, (b) 80 to 20 mol % monoethylenically unsaturated carboxylic acids and, optionally, (c) 0 to 30 mol % of other monoethylenically unsaturated monomers which can be copolymerised, and/or (d) 0 to 10 mol % monomers containing at least two ethylenically unsaturated non-conjugated double bonds in the molecule, in the presence of at least one sulphur, phosphorus and/or nitrogen compound having a reducing effect and of 0.05 to 30 wt %, relative to the monomers, of at least one surfactant in an aqueous medium and in the presence of initiators and, optionally, regulators. The invention further relates to the use of the copolymers or the copolymers comprising vinyl alcohol units obtained therefrom by hydrolysis and/or oxidation, as additives for washing and cleaning agents.
