    摘要: Linear phosphonitrilic chloride pleionomers having an average degree of polymerization of about 15 to 100 are conveniently prepared by heating linear phosphonitrilic chloride oligomers (e.g., (PNCl 2 ) 2-10 ) concurrently removing the phosphorus pentachloride vapors evolved. Heating temperatures of 275°C. -350°C and heating periods of from one to twenty and especially one to seven hours are used.
