    摘要: Cyclic phosphonitrilic halide trimer is made in high yield and at a rapid rate by adding NH.sub.3 or ammonium halide to a pyridine-hydrogen halide complex and adding phosphorus pentahalide and a solvent for the trimer (e.g. monochlorobenzene) and heating the mixture to above 90.degree. C. to form trimer which dissolves in the solvent and then separating the trimer-solvent phase from the residue phase of pyridine-hydrogen halide complex and recovering trimer from the solvent phase and recycling the pyridine-hydrogen halide phase to a subsequent procedure conducted in the same manner. The process can also be adapted to produce linear species in high yield also.

    摘要: Halophosphazene polymers such as linear phosphonitrilic chloride polymers are prepared in two stages by (i) heating a nitrogen source (e.g., NH.sub.3 ; NH.sub.4 Cl; etc.) with an excess of a phosphorus source (e.g., PCl.sub.5 ; PCl.sub.3 +Cl.sub.2 ; P+Cl.sub.2 ; etc.) so that hydrogen halide is evolved and halophosphazene is formed, and (ii) heating at least a portion of the halophosphazene with at least a stoichiometric amount (preferably an excess) of a nitrogen source (e.g., NH.sub.3 ; NH.sub.4 Cl; etc.) so that hydrogen halide is evolved and halophosphazene polymer of higher molecular weight is formed. Preferably, a third stage is utilized wherein the resultant halophosphazene polymer is then heated, most preferably in an inert solvent or diluent which enhances the fluidity of the reaction mixture, to increase the molecular weight of the polymer.

    摘要: A mixture of compounds of the formulas:[X--(PX.sub.2 .dbd.N).sub.n --PX.sub.3 ].sup.+ [R].sup.-andX--(PX.sub.2 .dbd.N).sub.n --POX.sub.2wherein X is a halogen atom, R is X or PX.sub.6 or both of them, and n is an integer, usually below about 15, is heated either with no other reactant or with a suitable phosphorus reactant such as PX.sub.5 ; PX.sub.3 +X.sub.2 ; P+X.sub.2 ; or a mixture of two or more such phosphorus reactants so that a halophosphazene having a --PX.sub.3.sup.+ end group is formed as one of the co-products of the reaction. This co-product is a substance having the general formula[X--(PX.sub.2 .dbd.N).sub.n --PX.sub.3 ].sup.+ [R].sup.-wherein X, R and n are as defined above. The other co-product is phosphoryl trihalide, POX.sub.3. In a second stage the resultant reaction product is heated with at least a stoichiometric amount (preferably, an excess) of a nitrogen source (e.g., NH.sub.3 ; NH.sub.4 Cl; etc.) so that hydrogen halide is evolved and halophosphazene polymer of a suitably high molecular weight is formed. By freeing the initial mixture of the --POX.sub.2 end group, the polymer formed in the second stage has greater linearity (less cross-linking) and reduced gel-forming tendencies.
