Abstract
PURPOSE: To prepare a title polymer adventageously from an industrial standpoint by a method wherein hexachlorocyclotriphosphonitrile or a mixture of this nitrile and octachlorocyclotetraphosphonitrile is heated in di-o-xylylethane.
CONSTITUTION: Hexachlorocyclotriphosphonitrile (3 PNC) or a mixture of 3 PNC and octachlorocyclotetraphosphonitrile (4 PNC) is polymerized in the presence or absensence of a catalyst in di-o-xylylethane (DXE) which is a high b.p. solvent. 1W1000 parts of DXE is used to 100 parts of 3 PNC or a mixture of 3 PNC and 4 PNC. After the reaction, the product is taken out from a reaction system by adding a solvent such as dry toluene or the like into a reactor and this toluene solution is poured into a large amount of n-hexane to precipitate phosphazene polymer.
