The present invention relates to a method for producing amphiphilic functionalized highly branched melamine-polyamine polymers by condensing melamine and optionally a melamine derivate having at least one different amine having at least two primary amino groups and optionally also with urea and/or at least one urea derivative and/or with at least one at least difunctional diisocyanate or polyisocyanate and/or at least one carbolic acid having at least two carboxyl groups or at least one derivative thereof, optionally quaternizing a portion of the amino groups of the polymer thereby obtained, reacting the polymer thus obtained with at least one compound capable of undergoing a condensation or addition reaction with amino groups, and optionally quaternizing at least part of the amino groups of the polymer obtained in the first step. The invention further relates to the amphiphilic functionalized highly branched melamine-polyamine polymers that can be obtained by the method according to the invention, and to the use thereof as surface active agents.

The present invention provides a composition comprising an amphiphile and an active ingredient whose solubility in water at 20&#xb0; C. is not more than 10 g/L. Likewise provided is an amphiphile comprising a hyperbranched polycarbonate which is joined to at least one linear or comb-type polymer, a process for preparing the amphiphile, and the use of the amphiphile in compositions comprising an active ingredient whose solubility in water at 20&#xb0; C. is not more than 10 g/L.

The present invention relates to a process for preparing high-functionality polyetherols by reacting at least one trifunctional or higher-functionality alcohol and if appropriate further di- and/or monofunctional alcohols and/or modifying reagents, with the aid of acidic catalysts, where the trifunctional or higher-functionality alcohol is not glycerol. The present invention further relates to high-functionality polyetherols obtainable by such a process and to the use of these high-functionality polyetherols as adhesion promoters, thixotropic agents, rheology modifiers of polymers, phase transfer reagents, micro- or nanocontainers for biologically active compounds, for example for active medical ingredients, biocides, herbicides or fungicides, as pigment dispersants, an additive in printing inks or as structural units for preparing polyaddition or polycondensation polymers or for treatment of seed.

Highly functional polyetherols and the production and use thereof

In a method for printing substrates with a printing ink and/or a printing varnish at least comprising solvents and binders, at least one of the binders comprises a polyetheramine polyol.
