Synthesis of a Polyphosphonium Salt by the Intramolecular Substitution of Poly (vinyl chloride) Containing Iminophosphoran Structure

Abstract

Cl atoms of poly (vinyl chloride) were substituted by azido groups and the obtained polymer was treated with triphenylphosphine to form the polymer containing iminophosphorane structure. From this polymer a polyphosphonium salt was synthesized by an intramolecular substitution. The structure of the polycation was invesigated.
