Title: HYPERBRANCHED POLYMERS AND OLIGOMERS COMPRISING TERMINAL AMINO GROUPS AS CURING AGENTS FOR EPOXY RESINS
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.
