Abstract:
The invention relates to a method for solubilizing hydrophobic active ingredients in an aqueous medium, characterized in that at least one hyperbranched polymer (A) is used as an auxiliary agent and can be obtained by reacting at least one hyperbranched polymer compound with at least one primary or secondary amino group per molecule (a), selected from (a1) hyperbranched polyamides and (a2) hyperbranched polyureas, having (b) at least one mono-, di-, or oligosaccharide.
Abstract:
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.
Abstract:
The invention relates to a composition containing an active substance which is soluble in water up to 10 g/L at 20 °C and a hyperbranched polyester based on a hydrophobic dicarboxylic acid and a trifunctional alcohol. The invention further relates to said hyperbranched polyester, to a method for the production thereof, and to the use thereof for solubilizing an active material which is soluble in water up to 10 g/L at 20 °C in aqueous solutions.
Abstract:
The invention relates to a method for producing hyperbranched polyhydroxybenzoic acid alkoxylates, comprising the following steps: (a) reacting at least one polyhydroxybenzoic acid ester with one or more alkylene oxides, optionally in the presence of a basic catalyst, (b) allowing the polyhydroxybenzoic acid ester alkoxylates formed in step (a) to react to form hyperbranched polyhydroxybenzoic acid alkoxylates under transesterification.
Abstract:
The invention relates to a method for producing highly functional polyetherols by reacting at least one trifunctional or higher functional alcohol and optionally further difunctional and/or monofunctional alcohols and/or modifying reagents with the help of acidic catalysts, the trifunctional or higher functional alcohol not being glycerol. The invention further relates to highly functional polyetherols that can be obtained by said method and to the use of said highly functional polyetherols as adhesion promoters, thixotropic agents, rheology modifiers of polymers, phase transfer reagents, microcontainers or nanocontainers for biologically active substances, for example for medical active substances, biocides, herbicides or fungicides, as pigment dispersants, additives in printing inks, as components for producing polyaddition or polycondensation polymers or for treating seeds.
