PHOSPHONITRILIC POLYMERS STABLE AT HIGH TEMPERATURES.
Abstract
A soluble P-O-P linked polymer of MW(n) 7000 was obtained and found to be stable to 317C. The P-O-P linked polymer in which the theoretical repeating unit is -P3N3(OC6H5)4)- appears slightly more stable than the polymer with the theoretical repeating unit -P3N3(C6H5)2(OC6H5)2O-. Polar solvents accelerate the reaction of P3N3C16 and hydroquinone at 80. A soluble polymer of MW(n)>6000 was prepared from P3N3(OC6H5)4C12 and disodiobisphenol A. Preliminary experiments directed toward preparing carborane-linked phosphonitrilic polymers are described. (Author)
