Abstract

Procedure for the controlled polymerization of hexachlorophosphazene, of formula (PNCl2) 3, at a temperature of approximately 200 to 350ºC, and for a time of between 30 minutes and 72 hours; characterized in that the polymerization of (PNCl2) 3 is carried out in the presence of 1 to 20% by weight of (PNCl2) 4, assessed by the weight of (PNCl2) 3 originally present, whereby gel formation is eliminated and They more easily control the percentage of conversion to polymer and the degree of polymerization.
