- the present invention refers to branched polyetheramine polyols with a Hazen colour number (determined according to DIN ISO 6271 ) in the range of from 100 to 600 (APHA), based on a polycondensation product of at least one trialkanolamine.
- Pigment dispersions are being used in many applications such as lacquers, printing pastes, printing inks, dying liquors and the like. Such pigment dispersions must meet numerous requirements such as effective assistance to optical properties, such as good colour reproduction of the pigment, high colour strength, high gloss, acceptable seeding and surface roughness, and alterable shades, in addition to good applicability profiles, high versatility with respect to applications, and requirements such as flocculation stability and good rheology. Furthermore, the ingredients for such pigment dispersions should be obtainable from starting materials readily available on the market.
- pigment dispersants are being provided with excellent properties.
- the synthesis requires a lot of starting materials and ingredients.
- Highly branched polyetheramine polyols are known as adhesion promoters (primers), thixotropic agents or flow improvers, see, e. g., WO 2009/047269.
- adhesion promoters primary
- thixotropic agents or flow improvers
- WO 2009/047269 adhesion promoters
- their applicability in pigment dispersions is disadvantageous. Their colour is sometimes unsatisfactory, and their applicability in pigment dispersions may have short-comings. It was therefore an objective of the instant invention to provide pigment dispersions with excellent properties that do not suffer from the disadvantages discussed above. It was further an objective to provide a process for manufacturing a pigment dispersion wherein said pigment dispersion does not suffer from the disadvantages discussed above. It was furthermore an objective of the instant invention to provide dispersants for pigment dispersions.
- branched polyetheramines defined at the outset have been found, hereinafter also referred to as (inventive) polyetheramine polyols (B) and as (inventive) branched polyetheramine polyols (B).

- Inventive branched polyetheramine polyols (B) can be successfully used for making inventive pigment dispersions.
- a further aspect of the present invention is a process for preparing inventive branched polyeth- eramine polyols (B), also being referred to as "inventive process”.
- the inventive process comprises the step of subjecting at least one trialkanolamine to polycondensation under catalysis of at least one catalyst selected from H3PO3 and hypophosphoric acid (H3PO2), characterized in that the temperature during polycondensation does not exceed 215 °C, and that said polycondensation is carried out in an atmosphere of an inert gas.
- inert gas examples include nitrogen and noble gases such as argon.
- At least one trialkanolamines will be subjected to polycondensation, for example selected from tri-C2-C4-alkanol-amines, with the alkanol groups in trialkanolamine being different or preferably identical.
- Trialkanolamine can be subjected to polycondensation or to co-polycondensation, either with one or more trialkanolamine or with one or more dialkanolamines.
- suitable trialkanolamines are triethanolamine, tripro- panolamine, triisopropanolamine and tributanolamine.
- dialkanolamines examples include ⁇ , ⁇ -diethanolamine, N,N-di-n-propanolamine, ⁇ , ⁇ -diisopropanolamine, N,N-di-n- butanolamine, N,N'-C2-C8-(jo-hydroxyalkylpiperidine, and polyetherols being based on ethylene oxide and/or propylene oxide.
- polyetheramine polyol (B) can be obtained by polycondensation of at least one of triethanolamine, triisopropanolamine and tri-n-propanolamine, or mixtures of at least two of triethanolamine, triisopropanolamine and tri-n-propanolamine. Preference is given to make polyetheramine polyol (B) by polycondensation of either triethanolamine or triisopropanolamine or a mixture of triethanolamine and triisopropanolamine, without using a diol.
- the term polycondensation also refers to co- polycondensation of more than one trialkanolamine and to co-polycondensations with at least one diol.
- the catalyst, H3PO3 or hypophosphoric acid (H3PO2) can be applied in bulk or as aqueous so- lution.
- the catalyst, H3PO3 or hypophosphoric acid (H3PO2) is added generally in an amount of 0.001 to 10 mole-%, preferably of 0.005 to 7, more preferably 0.01 to 5 mol-%, based on the amount of the trialkanolamine.
- the inventive process can be carried out by using a solvent.
- solvents that can be used to perform the inventive process are aromatic and/or (cyclo)aliphatic hydrocarbons and their mixtures, halogenated hydrocarbons, ketones, esters, and ethers.
- aromatic hydrocarbons Preference is given to aromatic hydrocarbons, (cyclo)aliphatic hydrocarbons, alkyl esters of alkanoic acids, ketones, alkoxylated alkyl esters of alkanoic acids, and mixtures thereof.
- Particularly preferred are mon- oalkylated or polyalkylated benzenes and naphthalenes, ketones, alkyl esters of alkanoic acids, and alkoxylated alkyl esters of alkanoic acids and mixtures thereof.
- Preferred aromatic hydrocarbon mixtures are those predominantly comprising aromatic C7 to CM hydrocarbons and possibly encompassing a boiling range from 1 10 to 300 °C, particular preference being given to toluene, 0-, m- or p-xylene, trimethylbenzene isomers, tetra- methylbenzene isomers, ethylbenzene, cumene, tetrahydronaphthalene, and mixtures comprising them.

- the inventive process can be carried out at a pressure in the range of from 0.5 bar to 20 bar, while normal pressure being preferred. In a preferred embodiment, the inventive process is being performed at normal pressure.
- the inventive process is preferably followed by removal or blow-off of residual monomers, for example, by distilling them off at normal pressure or at reduced pressure, e. g., in the range of from 0.1 to 0.5 bar.
- water or other volatile products released during the polycondensation can be removed from the reaction mixture in order to accelerate the reaction, such removal being accomplished by distillation, for example, and optionally under reduced pressure.
- the removal of water or of other low molecular mass reaction by-products can also be assisted by passing through the reaction mixture a stream of gas which is substantially inert under the reaction conditions (stripping), such as nitrogen, for example, or a noble gas such as helium, neon or argon, for example.
- Inventive branched polyetheramine polyols (B) that are prepared at up to 215 °C are typically stable at room temperature for a prolonged period, such as for at least 10 weeks, for example, without exhibiting instances of clouding, precipitation and/or significant increase in viscosity.
