Abstract
Método para la obtención de polidiclorofosfazeno [NPC12]n lineal (I) con peso molecular del orden de 2 106 a partir directamente de NH4Cl y PC15 en presencia de CaS04.H20 y HS03(NH2) como promotores. El método produce el polímero con un rendimiento entre el 30 y el 40 % basado en el PC15, con un coste muy reducido respecto de los métodos anteriores. El [NPC12]n se ha caracterizado a través de sus derivados [NP(02C12E8)]n y [NP(OCH2CF3)2]n.
