摘要

The voltage stability of crosslinked compositions of fluorocarbon polymers and conductive carbon black that exhibit a positive temperature coefficient of resistance can be improved by incorporating into the composition prior to its crosslinking an effective amount of a polymerizable polyethylenically unsaturated monomer such as, for example, triallylisocyanurate.
