    Abstract: Polymers containing acid groups are modified by reaction of(a) polymers which comprise at least 5% by weight of a copolymerized monoethylenically unsaturated monomer containing acid groups, have molar masses of from 200 to 100,000 and are obtainable by free-radical polymerization of monoethylenically unsaturated acids in aqueous solution in the presence or absence of other monoethylenically unsaturated monomers and in the presence of at least 4% by weight, based on the monomers used in the polymerization, of a water-soluble sulfur compound in which the sulfur is in the oxidation state +4,with(b) polyalkylene glycols which are end-capped at one end, alkylpolyalkylene glycol amines or mixtures thereof, or mixtures of at least one of the two compounds specified with up to 30% by weight, based on the mixtures, of ammonia, amines, alcohols, hydroxycarboxylic acids or aminocarboxylic acidsat up to 250° C.

    Abstract: Disclosed are compounds of the general formula: (see fig. I) where A is -NO2 or -NH2 B is -CH2-, -CH2-CHR1-, -CH2-CHR1-CH2-, -CH=, -CH=CR1- or -CH=CR1-CH=, R1 being -H, -Cl, -Br or -CH3, D is (see fig. II) or (see fig. III), depending on the terminal group B, X is -H, -Cl or -Br Y is -H, C1-C7-alkyl, -Cl, -Br, -CN, -CONH2 or -CO2R2, where R2 is H, C1-C6-alkyl, C5- or C6-cycloalkyl, C1-C4-alkoxy-C2-C4-alkyl, C1-C4-alkylmercapto-C2-C4-alkyl, propargyl, benzyl, .alpha.-phenylethyl, .alpha.-pehenylpropyl, C2-C4-alkyl which is monosubstituted, disubstituted or trisubstituted by F or Cl, or CH3-substituted or Cl-substituted allyl, and Z is -COOR2, -CONR3R4, (see fig. IV) or -COR2, where R3 and R4 are each H or C1-C4-alkyl or together form a 5-membered or 6-membered cycloaliphatic ring whose carbon chain may be interrupted by an oxygen atom. These compounds are useful as intermediates for the preparation of compounds of the same formula where A is (see fig. V), which are useful as herbicides.
