ABSTRACT:
The process according to the invention is performed by reaction of epoxide resins with primary and/or secondary polyamines with simultaneous quaternizing by means of aromatic and aliphatic polysulfonic esters, halogen-free organic phosphoric esters, or organic compounds which contain at least 1 chlorine or bromine atom, and which are free from -COOH groups and corresponding salt groups. The crosslinked plastics thus obtained are distinguished by an improved electrical conductivity.
