Abstract
Abstract A high polymer composition comprising a salt constituted from an integral type of polycationic polymer containing in its principal repeating unit a quarternarized nitrogen atom, which is a member of a saturated heterocyclic ring acting as a side chain, and a linking unit in its principal chain, an anion radical of a tetracyano compound and a neutral tetracyano compound in appropriate amounts such that the electroconductivity is greater than 10 7 cm 1. For practical uses it has very excellent chemical, physical and electrical porperties.
