Abstract

Procedimiento para la obtención de copolímuros de poli(fosfazeno) de elevado peso molecular, que poseen unidades distribuidas al azar, de fórmula en las que A representa un radical monovalente elegido del grupo consistente en F(CH2)pCH20- y H(CF2)pCH20- y p es un entero de 1 a 9; B representa un radical monovalente elegido del grupo consistente en RC6H40- y RZC6H40- en donde R se elige del grupo consistente en H(CH2)q y F(CF2)q, en donde q es 0-5 y Z representa un miembro divalente del grupo consistente en -CH2-, -0-, -NH-, y -NR''-, en donde R'' es un radical monovalente seleccionado del grupo consistente en H(CH2)q- y F(CF2)q-, en donde q es 0-5 y la relación de A:B está comprendida entre 1:9 y 3:1; caracterizado porque se hace reaccionar una sal de metal alcalino de un flúor-alcóxido y uua sal de metal alcalino de un arilóxido, con poli(diclorofosfazeno) en solución; y a continuación se recupera el copolímero resultante.
