Zusammenfassung: | An ionic polymer, suitable as an organic di-electric is derived from a partially substituted derivative of phosphonitrilic chloride, suitably by reaction with dimethylformamide. The partially substituted phosphonitrilic chloride may be the di- or tri-substituted dimethylamine derivative, methoxyl derivatives or the di- or tetra-phenyl derivatives. A high M.W. polymer other than the ionic polymer may be mixed with the ionic polymer. In the examples the above mentioned partial substitution products of phosphonitrilic chloride in dimethylformamide are added to solutions of polyacrylonitrile in dimethylformamide and the solution heated to cause reaction between the dimethylformamide and the partially substituted phosphonitrilic chloride. Films of the resulting product may be cast on glass plates. |
