    摘要： 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.

    摘要： 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.
