Linear polychlorophosphazenes possessing a dichlorothiophosphoryl terminal group, process for preparation of said compounds and utilization thereof

摘要

Linear polychlorophosphazenes having a dichlorothiophosphoryl terminal group and corresponding to the formula ##EQU1## 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.P PThese polymers can be applied to all the uses of the classical polychlorophosphazenes.
