    Abstract: The invention relates to the use of hyperbranched polymers or oligomers comprising terminal primary and/or secondary amino groups as curing agents for epoxy resins. The invention further relates to a composition containing such polymers or oligomers, an uncured or only partially cured epoxy resin, and at least one optional curing agent for epoxy resins, as well as a cured epoxy resin that can be obtained by curing said components. The invention finally relates to a method for curing epoxy resins. In said method, an uncured or only partially cured epoxy resin is brought to a temperature of 5 to 150°C or is exposed to microwave radiation along with at least one polymer or oligomer according to the definition above and at least one optional conventional curing agent for epoxy resins.

    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 biolo-gically 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.
