ABSTRACT:
A process for preparing an electrical device which has a conductive polymer exhibiting PTC behavior. The cross-linking may be to a level of 50 to 100 Mrad or higher for devices designed to withstand high voltage test conditions. The device may be a laminar device having a center layer of higher resistivity than two surrounding layers.
