Electrical device comprising a cross-linked layer

Abstract

An electrical device includes at least one cross-linked layer obtained from a polymer composition that has: at least one polymer comprising one or more epoxy function(s), and at least one cross-linking agent. The cross-linking agent is selected from: a non-aromatic cyclic amine, an imidazole of formula (I) where R1 and R2 independently represent a hydrogen atom or a hydrocarbon group, R3 and R4 independently represent a hydrogen atom or a hydrocarbon group, or R3 and R4 form, together with the carbon atoms of the imidazole ring to which they are attached, a ring, with the imidazole being associated with a cross-linking co-agent having at least one reactive function capable of reacting with the epoxy function of said polymer, and, a mixture thereof.
