Estimating the term…
The invention relates to a curable composition comprising one or more epoxy compounds, one or more anionically curing catalysts, and an addition of one or more dendritic polymers, selected from the group consisting of the dendritic polyester polymers, the dendritic polyesteramide polymers, and the dendritic polymers based on 1,3,5-tris-alkanol-substituted cyanuric acid. These dendritic polymers improve mechanical properties, in particular the toughness of the cured epoxy resin.
A curable composition, comprising one or more epoxy compounds, one or more anionically curing catalysts for the curing of epoxy compounds, and an addition of one or more dendritic polymers, selected from the group consisting of the dendritic polyester polymers, the dendritic polyesteramide polymers, and the dendritic polymers based on 1,3,5-tris-alkanol-substituted cyanuric acid.
The use of dendritic polymers selected from the group consisting of the dendritic polyester polymers, the dendritic polyesteramide polymers, and the dendritic polymers based on 1,3,5-tris-alkanol-substituted cyanuric acid, in curable compositions made of epoxy compounds and of anionically curing catalysts for the curing of epoxy compounds to improve the toughness of the cured epoxy resin.
