Abstract: The agent for preventing the flooding of coloured pigments from polymer emulsion (dispersion) paints, polymer renders or distempers that contain cellulose ether is based on a block polymer of a di- or polyamine and added alkylene oxide units. The block polymer conforms to the formula II. The substituents in formula II are as defined in Claim 1. The agent is used for aqueous binder-containing paints or renders that contain cellulose ether and are to be coloured or are already coloured and are or would be white without the addition of coloured pigment.

Abstract: New 3,3-diphosphono-pimelic acid and its derivs. have the formula (I): (R2O3P)2C(CH2-CH2-COOR)2 (I) (where R, which are opt. identical, are opt. halogen-substd. 1-18C alkyl gps., H, alkali- or NH4 ions). In pref. (I), the alkyl gps. are 1-3x substd. by halogen, esp. Cl and/or Br; alkyl gps. contain 1-8C and alkali ions are Na and/or K ions. (I) where R are only opt. halogen-substd. alkyl are used as plasticisers for PVC and also impart flame-resistant or self-extinguishing properties. (I) where R are only H, alkali and/or NH4 ions are used as (i) retarders for gypsum setting and (ii) complex-formers for metal ions, e.g. Fe and alkaline earth metals. Plasticiser concn. in PVC may be 20-50wt.%. Gypsum setting retarders are superior to citric acid and are used in 0.06-0.09wt.% concn. The complex-formers can be used for cleaning glass articles, e.g., in bottle washing compsns. In an example, 3,3-diphosphono-pimelic acid was prepd. by (i) reacting 4 mol. Et acrylate with 2 mol. tetra-Et methane-diphosphonate and (ii) acidolysis of the hexa-Et ester obtd.
