PHOSPHONITRILIC POLYMERS STABLE AT HIGH TEMPERATURES.
Abstract
The objective of this investigation is the development of new thermoplastic and thermosetting resins from phosphonitrilic chloride trimer for high temperature electrical applications. The preparation of the tetraphenoxydichlorophosphonitrile trimer was scaled up to yield a total of seven pounds of this monomer. Additional quantities of other monomers were also prepared. Copolymerization of phosphonitriles of reduced functionality has been carried out to give polymers containing the bridging roups -O-, p,p'-OC6H4OC6H4O-, and p,p'-OC6H4C(CH3)2C6H4O-. The introduction of the borate function onto the trimeric phosphonitrile ring has been carried out. (Author)
