Definitions
- the invention relates to novel aminoplast-ether copolymers, a process for their preparation and their use as dispersants or stabilizers.
- aminoplast units usually used as crosslinking agents in the curing of paints and varnishes or polymers can be used to link chemically different structures.
- Corresponding products with alkyl, ether, ester, amine or urethane groups can be produced.
- dispersants are surface-active substances that disperse a powdery substance, e.g. B. a pigment or filler, in one liquid dispersion medium by lowering the interfacial tension between the two components. Dispersants facilitate the mechanical breaking up of agglomerates in primary particles. Furthermore, dispersants protect the primary particles formed by forming a protective colloid shell or an electrochemical double layer against reagglomeration or flocculation. If specific measures against flocculation or against sedimentation are taken that lead to a steric and / or electrostatic stabilization of the pigment particles with each other, one speaks of stabilizing agents.
- Dispersants facilitate the incorporation of pigments and fillers in the manufacture of paints and varnishes, which, as important formulation components, determine the visual appearance and the physicochemical properties of coatings. In addition, dispersants can increase the compatibility between chemically different types of polymers.
- US-A-5,629,373 and US-A-5, 914, 373 describe water-soluble aminoplast-ether copolymers with polar base polymer units and polar side chains which are used as water-soluble associative thickeners.
- WO 02/12363 AI (prior art according to Art. 53 (2) EPC) describes a special form of the association thickeners described in US Pat. No. 5,914,373.

- aqueous architectural paints or latex paints have a special stability when tinting with color concentrates.
- the term "associative thicker" is explained on page 1, last paragraph as:
- pigment and filler dispersions in solvent-containing systems are stabilized essentially by steric hindrance, and predominantly electrochemically in aqueous systems.
- aqueous systems in particular, numerous problems can arise during production and processing, which are described in Juan M. Oyarz ⁇ n, Handbuch der Pigment für, Vincentz-Verlag, 1998:
- Anionic, cationic, nonionic or amphoteric dispersants optionally in polymeric form, are usually used.
- Additives based on mineral oils, polyacrylates, modified silicones and alkylphenol ethoxylates are used in particular in aqueous systems.
- mineral oils reduce the gloss and transparency of the coating and tend to separate in low-pigment systems.
- a disadvantage of modified natural products is their low water resistance and biostability.
- the use of alkylphenol ethoxylates is ecotoxicologically questionable, while silicones e.g. T. Show intermediate adhesion and crater problems (Schmitz et al., Aid & Lacke, 3/2000).
- the object of the present invention was to overcome the aforementioned disadvantages of the prior art and to provide new dispersants and stabilizers which are simple to prepare and which display exceptionally good application properties, particularly in aqueous systems.
