PHOSPHONITRILIC POLYMERS STABLE AT HIGH TEMPERATURES.
Abstract
The objective of the investigation is the development of new thermoplastic and thermosetting resins from phosphonitrilic chloride trimer for high temperature electrical applications. Polymers were prepared by linking together bifunctional phenyl-and phenoxysubstituted trimeric phosphonitriles. Linking groups include oxygen, nitrogen, hydroquinone, tetrahydroxyaromatics and groups derived from the reaction of phosphonitrile isocyanates with glycols or diamines. The oxygen-linked and hydroquinone-linked polymers appear most promising. New syntheses of phosphonitriles of reduced functionality are reported. (Author)
