    Abstract: Process for the preparation of pure aromatic o-hydroxy-carboxylic acid aryl amides by condensing an aromatic o-hydroxy-carboxylic acid with an aryl amine in the presence of phosphorus chlorides in an organic solvent or diluent, which process comprises treating the reaction mixture or the reaction product with 1 to 25 %, calculated on the weight of the reaction product, of an aliphatic amino-polycarboxylic acid as chelate forming agent. It is not necessary to purify the products, because they are obtained in such a pure form that they can be used directly as coupling components for azo pigments.

    Abstract: in which X, Y and Z stand for a hydrogen and/or halogen atom with the proviso that at least one of the X, Y and Z substituents stands for a halogen atom, R stands for a carboxyhalide radical, a carboxylic group, ester group, nitrile group or anhydride group, and the mole fraction m stands for a number greater than zero and smaller than 1.

    The invention provides novel oligomers and/or polymers containing carboxylic and hydroxylic groups - the latter groups being partially lactonized, if desired - and a predominant proportion of C-C bonds in their principal chain. The oligomers and/or polymers are produced by hydrolyzing halogenated copolymers which have substantially between 5 and 60 weight % of halogen therein and a principal chain based on structural units, in any desirable sequential arrangement, of the following general formulae I and II or I and III

    Abstract: SOLID LINEAR OR CROSS-LINKED HYDROXYCARBOXYLIC ACID POLYMERS WHICH IN THE MAIN CHAIN HAVE PREDOMINANTLY CARBON-TO-CARBON BONDS, ALL, OR THE MAJOR PART OF THE UNITS IN THE MAIN CHAIN, HAVING THE FORMULA

    -CH2-C(-R1)(-COO-A)-, AND -CH2-C(-R)(-CH2-OH)-, OR

    -CH2-CH-OH

    WHEREIN R AND R'' ARE THE SAME OR DIFFERENT AND ARE ALKYL HAVING 1 TO 6 CARBON ATOMS OR HYDROGEN AND WHEREIN R1 MAY ALSO BE HALOGEN. IN ADDITION, THERE MAY BE A MINOR AMOUNT, RELATIVE TO THE NUMBER OF THE UNITS (I), (II) AND (III), OF UNITS OF THE FORMULA

    -C(-R)(-COO-A)-C(-R)(-COO-A)-

    WHEREIN A IS HYDROGEN, ONE VALENCE OF A MONOVALENT OR A POLYVALENT METAL OF AMMONIUM. ALL OF THESE UNITS ARE ARRANGED IN RANDOM SEQUENCE AND THEIR NUMBE IS SUCH THAT THE RATIO OF CARBOXYL OR CARBOXYLATE OT HYDROXYL GROUPS IS BETWEEN 1.1 AND 16. THE MINIMUM DEGREE OF POLYMERIZATION IS 3; PREFERABLY, IT IS NOT ABOVE 5000, AND PARTICULARLY BETWEEN 3 AND 600. THE POLYMERS ARE VALUABLE AS COMPLEXING AGENTS.
