Embodiment 1
[0058] 20 parts of Epikote 1001 and 44 parts of Jeffamine M 1000 were mixed, and the mixture was heated at 140° C. for about 4 hours under a nitrogen atmosphere until no epoxy group could be detected by, for example, nuclear magnetic resonance (NMR) experiments. The composition of the reaction solution is chosen such that one mole of primary amino groups is used per mole of epoxy groups. A yellowish, clear and viscous reaction solution was obtained. The product crystallizes out after a period of time and is used as a wetting and dispersing agent, either heated or diluted with a suitable solvent.
[0059] Epikote 1001, commercially available from Shell AG, is a relatively high molecular weight solid epoxy resin based on bisphenol A.
Embodiment 2-4
[0061] Using the method of Example 1, the epoxide was further reacted with the amine. Table 1 summarizes these experiments. These products and the ratio of (poly)epoxide to amine are chosen such that the same mole fraction of amino and epoxy groups is used. In order to ensure this ratio, the epoxy equivalent weight per (poly)epoxide and the number of amino groups per amine are determined.

Embodiment 5
[0067] At about 60°C, with 6.4 parts of phosphate monoester (HO) 2 PO(OR 1 ) to salify 30 parts of the reaction product from Example 2 in which R 1 = Butoxypolyphenylene glycol (AcN ~ 112.5 mg KOH / g; hereinafter referred to as Phosphate A), the reaction product from Example 2 has an amino group number (AmN) of 24 mg KOH / g. A clear, viscous and brown reaction solution was obtained. The salinity value for this example is 1.
