Abstract
Linear polychlorophosphazenes having a dichlorothiophosphoryl terminal group and corresponding to the formula EQU Cl.sub.2 (S)P--NPCl.sub.2 ].sub.n Cl wherein n is a number equal to or more than 4. The aforesaid linear polychlorophosphazenes are prepared by polycondensing P.sub.2 NSCl.sub.5 by heating under conditions adequate for liberating PSCl.sub.3. These polymers can be applied to all the uses of the classical polychlorophosphazenes.
