foerfarande foer masspolykondensation av n - diklorofosforyl - eller n - diklorotiofosforyl - p - triklorofosfasen.

摘要

The invention relates to a process for the polycondensation by weight of n - dichlorophosphoryl - or n - dichlorothiophosphoryl - p - trichlorophosphazene. / p & & p & this process consists in carrying out polycondensation, with stirring, into a reactor equipped with a system for preventing the accumulation of the polycondensate on the stirrer. / p & & p & it is thus possible to obtain polycondensates of very high molecular mass without crosslinking.
